In his viral video, Mrwhosetheboss tests a keyboard PC, a 16 mm mechanical keyboard, a 6.4 mm pair of earbuds, paintable light, and more. Here is every device, its thickness, his verdict, and the lessons for anyone buying gear for work.
In "I spent $12,000 on the THINNEST Tech," Arun Maini, the creator behind the Mrwhosetheboss channel, buys and tests the slimmest gadgets he can find in 2026. He starts with a desk setup: a full PC built into a keyboard, a 16 mm mechanical keyboard, a fold-flat mouse, and a 14.3 mm portable monitor. Then he pits that whole setup against a 10 mm laptop.
After that he works through pocket tech that sticks to the back of a phone (a power bank, earbuds, an e-reader), plus a 3.1 mm laptop stand, a 2.2 mm phone back, a pen with a 0.3 mm tip, and light you can spray onto a surface. The video is sponsored by LG, whose wallpaper-style OLED TV gets its own segment. His running conclusion: thinner is impressive, but it is not automatically better.

He sets the premise in the first few seconds:
I've just spent $12,000 buying the next generation of thin tech.
Here is every device in the video, in the order it appears. Thicknesses and prices are the figures stated or measured on camera. Some brand names come from the video's audio, so check the spelling before you search for one.
| Device | Thickness (per the video) | What it is | His verdict, in short |
|---|---|---|---|
| HP keyboard PC | 20.1 mm | A desktop-class PC (HP says up to 64 GB of RAM) inside a keyboard. One cable runs to the monitor, and it has an internal battery. | Ran Rocket League in 4K at max settings and the keys feel good, but the fans are very loud. He calls it a louder bottom half of a laptop that still costs about $3,000. |
| Lofree Edge | 16 mm | A full mechanical keyboard | A clear favorite. Satisfying clicks, a low wrist angle, and easy to carry in a bag. |
| Fold-flat magnetic mouse | 14.1 mm flat | A mouse that pops into shape with a magnet and uses a touch strip instead of a scroll wheel | Clicks feel good and it works better than it looks, but scrolling is less precise. He questions whether it beats a laptop trackpad. |
| Sotsu FlipAction Elite monitor | 14.3 mm | A 16-inch portable monitor, just over 4K, aluminum, with a built-in stand that rotates 180°. It auto-rotates and has USB-C, mini HDMI, and an SD card reader. | "Such a sick product." Very bright and sharp, though it runs at 60 Hz and can't match OLED contrast. |
| ASUS ZenBook S14 | About 10 mm | A light Windows laptop with an OLED screen | Creaky plastic, but a 120 Hz OLED screen, quieter fans, and a good trackpad. It beat the desk setup. |
| LG OLED evo AI W6 (sponsor) | About 9 mm | A "wallpaper" TV that sits flush on the wall, with a wireless Zero Connect box | Sponsored segment. He installs it at his in-laws' house as a surprise. |
| Gift-card multi-tool | 7.4 mm | 14 tools in a card-sized body, including a box cutter, bottle opener, and pliers | Surprisingly useful. He jokes that he now understands why dads love multi-tools. |
| Gamer Card console | 6.7 mm | A handheld sold off a rack like a gift card, with six indie games preloaded | Great screen, weak controls. He wouldn't buy one on impulse and wonders if it is "too thin for its own good." |
| Xiaomi ultra-thin power bank | 6.5 mm | A 5,000 mAh magnetic (MagSafe-style) battery that charges wired or wirelessly and can top up two devices at once | The most stylish phone power bank he has seen, but wireless charging from a small battery wastes energy. |
| Fold-out earbuds | 6.4 mm with case | Spring-loaded earbuds whose case sticks to the phone and draws power from its USB-C port | "A big fan." The sound is about as good as wired EarPods, they are very light, and they are hard to lose. |
| Snap-on e-reader | 5.5 mm | An E Ink reader that clips magnetically to the back of a phone | Distraction-free, one-handed, and about 14 days per charge. He likes it more than he expected. The newer Pro version is thicker and doesn't line up with the phone. |
| MOFT laptop stand | About 3.1 mm | A stick-on, load-bearing stand with two heights | "That's awesome." It fixes the laptop's ergonomics and adds no real thickness. |
| Nomad phone back | 2.2 mm | A magnetic leather back rather than a full case | The idea works, but this one feels plasticky and scratched under his fingernail. |
| Jetstream Edge pen | 0.3 mm tip | Billed as the ballpoint with the world's thinnest nib | He writes a far smaller "subscribe" than he could with a normal pen. "Next-level." |
| LumiLor paintable light | A few layers of paint | Four sprayed layers that light up any surface when powered | The finale. He paints a glowing PS5 and calls it "way better than I expected." |
No, at least not in his test. He lays the keyboard PC, mouse, and portable monitor next to the ASUS ZenBook S14 and runs Rocket League on both. The laptop loads slightly faster and runs at twice the frame rate, because its screen is 120 Hz against the monitor's 60 Hz. It is also much quieter, and its OLED screen shows deeper blacks. His summary:
In the pursuit of trying to build the thinnest desk setup, we've actually just built a deconstructed laptop, and that is actually less good than just buying the real thing.
The laptop's one weak spot is posture, and later in the video he fixes it with the 3.1 mm MOFT stand. A thin laptop plus a near-invisible stand ends up as the most practical "thin desk" in the video.
About halfway through, the video says clearly that the LG OLED evo AI W6 TV is its sponsor. Arun takes it to his in-laws' house as a surprise living-room upgrade. On camera he measures it at around 9 mm and points out that it sits completely flush with the wall. He also covers the wireless Zero Connect box (devices plug into the box, which streams to the screen from up to 10 m away), the Alpha 11 AI processor, and the art-display mode that gives the TV its "wallpaper" name.
That is a paid segment, so treat it as LG's pitch delivered by a creator, not as an independent review. It has no head-to-head testing like the laptop comparison. If you are shopping for that TV, look for independent reviews as well.
The best part of the video is how often a thin product had to give something up. That pattern holds for almost any hardware decision:
| Trade-off | Where it shows up in the video |
|---|---|
| Noise and heat | Packing desktop parts into a 20 mm keyboard needs loud fans |
| Ergonomics and controls | The mouse loses its scroll wheel, and the gift-card console's buttons are hard to use |
| Durability and feel | The ZenBook creaks, and the 2.2 mm phone back scratches easily |
| Battery capacity | A 6.5 mm power bank holds 5,000 mAh, and wireless charging wastes some of it |
| Simplicity | A thin "setup" of four parts loses to one integrated laptop |
He even admits the video is changing his own taste:
What can I say? My standards for thinness are going up. Or down.
Most owners will not buy a gift-card console for the office. The video still works as a buying guide for work gear:
If you are kitting out a small team, our guide to AI tools for solopreneurs covers the software side of a lean setup.
One detail stands out: the sponsored TV is sold on its "AI" processor and "dual AI engine." AI is moving into devices to sharpen pictures and tune sound. That makes products nicer to use, but it doesn't take a single task off a business owner's list.
For a small business, the useful kind of AI is the kind that does work: answering the phone when no one can, replying to customer emails, following up with leads, and keeping the website visible in AI search. The hardware keeps getting thinner. The value is shifting to software that does the job, whatever device you run it on.

It's "I spent $12,000 on the THINNEST Tech," published September 8, 2026, in which Arun Maini tests 2026's slimmest gadgets, from a PC built into a keyboard to paintable light.
Among standalone devices, the MOFT laptop stand at about 3.1 mm and the Nomad phone back at 2.2 mm were the thinnest. The LumiLor paintable light is just layers of paint, and the Jetstream Edge pen has a 0.3 mm tip.
No. The ASUS ZenBook S14 loaded Rocket League slightly faster, ran at double the frame rate on its 120 Hz OLED screen, and was much quieter than the keyboard PC and portable monitor.
LG sponsored it. The sponsor segment features the LG OLED evo AI W6 wallpaper TV, which he measured at around 9 mm and installed at his in-laws' house.
He was most positive about the Lofree Edge mechanical keyboard, the fold-out earbuds that stick to the phone, the snap-on e-reader, the MOFT laptop stand, and the LumiLor paintable light.
Buy for the job, not the spec. One good thin laptop beat a set of thin accessories, and a cheap stand improved comfort most. AI built into devices improves the experience, but business value comes from AI that does tasks.
