But the most interesting of the bunch is the Xreal Project Aura smart glasses, which support full hand gesture support as well as mixed reality view for Android apps available through the Play Store. These smart glasses were first showcased in December 2025, but Xreal confirmed earlier today that the Project Aura smart glasses will hit the shelves in 2026.

The Project AURA smart glasses by Xreal come equipped with a built-in display that offers a 70° field of view, which the company claims is the largest FOV that has ever been offered on a pair of AR glasses. Thanks to the built-in display, you can overlay digital content in your sight while still having a clear view of the world around you. The company notes that you can run multiple app windows and get the full Android app experience without any hacks.

This is the full-blown Android experience that we are talking about. So far, the Xreal smart glasses that have been available to customers have run a custom version of Xreal’s in-house software that is launched through an app. The only way you could access Android on the Xreal smart glasses is by mirroring them through your phone or by connecting them to a PC in order to run Windows or macOS.
They have supported multi-windows, offering a massive digital canvas for you to run different apps side by side. These virtual windows can be accessed either affixed in the air, or by making them track your head movements. With the Project Aura, Xreal is getting rid of the software limitations by making these smart glasses run the native Android XR experience, with plenty of Gemini experiences in tow. So far, the demo videos released by the company have shown these glasses connecting to a smartphone-shaped puck through a cable.

Unlike the audio glasses that Google showed off earlier today, these glasses won’t be able to run the full Android XR experience without a wired connection due to the processing limitations. Talking about processing, Qualcomm will supply the chip for the Xreal Project Aura smart glasses, promising a dual-chip design which includes a Snapdragon silicon as well as a custom X1S processor.
The first computer my family owned was an 80286 IBM clone, and it had lots of ports, none of which looked the same. There was a big 5-pin DIN for the keyboard, a serial port, a parallel port, a game port for our joystick, and of course, the VGA port for the monitor.
In comparison, a modern computer has much less diversity in the port department. Not only are there fewer types of ports, but the total number may be quite low as well. When we move to modern laptops, it can be much more minimalist. Some laptops have just a single port on the entire machine! Is this a bad thing? As with anything, the extremes are rarely ideal, but I’d say overall, this has been a pretty positive development for PCs.
The port explosion era was never sustainable
It was more like a port infection
You see, the reason we had so many ports for so long is that people kept inventing new interfaces to make up for the shortcomings of existing ones. However, instead of the newer, better interfaces making the old ones obsolete, they just became additive as perfectly summarized in this classic XKCD comic.

In laptops, the need for so many ports reached ridiculous heights. In this video posted by X user PC Philanthropy, you can see his Sager/Clevo D9T absolutely packed with all the trimmings leading to a rather massive laptop.
It is undeniably a cool machine, but obviously goes against the principle of portable computing. Also, every port you install means power and space that could have been taken up by something else. That’s true for laptops and desktops.

PC ports and motherboard I/O Trivia challenge
Think you know your USB from your PCIe? Put your connector knowledge to the test.
PortsStandardsHardwareConnectorsMotherboards
Which USB connector type is fully reversible, meaning it can be plugged in either way?
Correct! USB Type-C features a symmetrical oval design that lets you insert it in either orientation. Introduced in 2014, it has become the dominant connector for modern devices and supports everything from data transfer to video output and fast charging.
Not quite — the answer is USB Type-C. The older USB Type-A connector (the flat rectangular one) famously required you to flip it at least twice before getting it right. USB Type-C’s reversible design was one of its biggest selling points when it launched in 2014.
What does the ‘x16’ in a PCIe x16 slot refer to?
Exactly right! PCIe x16 means the slot has 16 data lanes, allowing significantly more bandwidth than smaller x1 or x4 slots. This is why discrete graphics cards almost always use x16 slots — they need that extra throughput to feed pixel data to your display.
Not quite — the ‘x16’ refers to the number of data lanes. More lanes mean more simultaneous data paths between the CPU and the card. Graphics cards use x16 slots because their massive data demands require all 16 of those lanes working together.
Which port on a motherboard is most commonly used to connect a display directly to the CPU’s integrated graphics?
That’s correct! The HDMI and DisplayPort connectors found on a motherboard’s rear I/O panel are wired directly to the CPU’s integrated graphics unit. If you have a discrete GPU installed, you should use that card’s outputs instead for best performance.
The right answer is the HDMI or DisplayPort connectors on the rear I/O panel. These ports bypass the discrete GPU entirely and tap into the CPU’s built-in graphics. It’s a common troubleshooting trap — plugging a monitor into the motherboard instead of the GPU and wondering why nothing works.
What is the primary function of the 24-pin ATX connector on a motherboard?
Spot on! The 24-pin ATX connector is the main power connector that delivers multiple voltage rails — including 3.3V, 5V, and 12V — from the power supply to the motherboard. Without it seated properly, your PC simply won’t power on at all.
The correct answer is delivering power from the PSU to the motherboard. The 24-pin ATX connector is the big wide plug you’ll find on every modern motherboard. It supplies several different voltage levels that the board distributes to components. PCIe cards get their supplemental power from separate 6- or 8-pin connectors directly from the PSU.
Which of the following rear I/O ports transmits both audio and video in a single cable and is most commonly found on modern motherboards?
Correct! HDMI carries both high-definition audio and video over a single cable, making it one of the most convenient display connectors available. It became standard on motherboards as integrated graphics improved, and modern versions support 4K and even 8K resolutions.
The answer is HDMI. VGA is analog-only and carries no audio, DVI-D is digital video only without audio, and S-Video is an older analog format. HDMI bundles both audio and video digitally, which is why it became the go-to connector for TVs, monitors, and motherboard rear panels alike.
What maximum theoretical data transfer speed does USB 3.2 Gen 2×2 support?
Impressive! USB 3.2 Gen 2×2 achieves 20 Gbps by using two 10 Gbps lanes simultaneously — that’s what the ‘2×2’ means. It requires a USB Type-C connector and is most commonly found on high-end motherboards, making it ideal for fast external SSDs.
The correct answer is 20 Gbps. The ‘2×2’ in the name is the key clue — it bonds two 10 Gbps channels together. USB naming got notoriously confusing around this era, with the same physical port potentially supporting very different speeds depending on the generation label printed in the spec sheet.
What is the role of the M.2 slot found on most modern motherboards?
Well done! M.2 is a compact form-factor slot that most commonly hosts NVMe SSDs, which connect via PCIe lanes for blazing-fast storage speeds. Some M.2 slots also support SATA-based SSDs and Wi-Fi/Bluetooth combo cards, making the slot surprisingly versatile.
The correct answer is housing compact storage drives or wireless cards. M.2 replaced the older mSATA standard and supports both PCIe NVMe drives and SATA drives depending on the slot’s keying. NVMe M.2 drives can achieve sequential read speeds many times faster than traditional SATA SSDs.
Which audio connector color on a standard PC rear I/O panel is designated for the main stereo line output to speakers or headphones?
That’s right! The green 3.5mm jack is the standard line-out port used for speakers and headphones in the PC audio color-coding scheme. Blue is line-in for recording, and pink is the microphone input — a color system that’s been consistent across PC motherboards for decades.
The correct answer is green. PC audio jacks follow a long-standing color convention: green for headphones and speakers, blue for line-in (recording from external sources), and pink for the microphone. It’s one of those legacy standards that has quietly persisted even as USB and digital audio have become more common.

USB-C (almost) solved the problem
So close, but not quite there yet
Released to the public in the mid ’90s, USB came to the rescue. The “U” is for “Universal” and for the most part USB has lived up to that promise. Now there was one port that handled data and power. More importantly, USB is fully backwards compatible. So if you plug a USB 1.1 device into a modern USB port, it should work. Whether you can get software drivers for it is another story, but it will talk to the host device.
USB-C has proven to be less universal than I’d like, and the situation is still far better than it used to be. A single USB-C port on one of my laptops can act as a video output for just about anything, even an old VGA monitor.

My smaller laptops don’t need special chargers anymore, and the latest laptops can pull 240W over USB-C, which is enough for all but the beefiest desktop replacement machines. There is no type of peripheral I can think of that doesn’t give you the option to use it over USB.
But the complaints aren’t so much that we only get USB these days, it’s more that we get so little of it.
Minimal I/O enables better hardware design
Harder, better, faster, stronger
When you only put a handful of USB-C ports on a mobile computer, you reap numerous benefits. The low profile of USB-C means the laptop can be thinner, and the frame can be a stronger and more rigid unibody design. Internally, you have room for more battery, larger performance components, or better cooling.

It also means the internals can be simpler, and cheaper to design and fabricate, though whether those savings are passed on to customers is another story altogether.
Wireless and cloud-first workflows reduce physical dependency
I guess they are “air” ports
Perhaps the first sign of major change was when smartphones dropped headphone jacks, but the fact is that wireless technologies are now good enough for most peripheral and data connections. So, there’s no need to connect them directly to a port on a computer. Which, in turn, means that there’s no reason to have as many ports on the computer in the first place.
I can’t remember the last time I used a wired mouse or keyboard, and I only use Ethernet for devices that need extremely high speeds, low latency, or improved reliability. For normal day-to-day use, modern Wi-Fi is just fine. So while your laptop might not have as many wired ports on the outside, those wireless chips on the inside still give it numerous connectivity options for audio, input, and data transfer.
You could even make the same argument about storage to some extent, with many thin and light systems leaning on cloud storage to make up for a lack of ports to connect external storage.

The MacBook Neo with the A18 Pro chip is Apple’s most affordable laptop yet, with all-day battery life and buttery-smooth performance in a thin and light profile.
The dongle backlash misses the bigger picture
The last bit of the port protest centers around dongles, but I never understood the complaints. Having one port that can be broken out into whatever ports you need using a little box is amazing. It makes ports optional and gives you the choice. If you never plug your laptop into anything, why deal with all the ports you’ll never use?
Likewise, if you only ever use ports with your laptop when you dock it at a desk, then you can just leave your dongle ready to go on your desk, but throwing a small dongle in your laptop sleeve or bag in case you might need it is a small price to pay for all the benefits of minimal IO.
