The moment you open the box, your brain short-circuits. Inside, there's nothing but what looks for all the world like a single high-end external keyboard. And yet, this is the entirety of the latest Windows 11 PC, the "HP EliteBoard G1a."
The "all-in-one keyboard PC," reminiscent of the MSX or Commodore 64 of yesteryear, has been resurrected with 2026 technology. Just 17mm thick and weighing roughly 700g. Inside this slim board sits a complete system: CPU, memory, storage, and even a cooling fan. Using it is simple. Just connect it to a monitor at your office or a TV in your hotel room with a single USB-C cable. In that instant, that spot becomes your office.

Don't write it off as "just smartphone-grade hardware on the inside." At its heart sits AMD's latest processor, the "Ryzen AI 300 Series (Krackan)." With NPU performance exceeding 50 TOPS, it's a high-spec machine that comfortably clears Microsoft's "Copilot+ PC" requirements.
Heavy Excel macro processing or local image-generation AI? It handles them with ease, the fan barely whispering. The thermal design is a work of art: an airflow system that draws air in through the gaps between the keys and exhausts it out the back means your fingertips never get hot, even during long typing sessions. "Keyboard on the outside, workstation on the inside." For any gadget lover, that gap is enough to bring on a knowing smirk.

The truly perverse thing about this product (and I mean that as a compliment) is that you can even add an optional built-in battery. In other words, unplug the power cable and the PC keeps running.
From the meeting room back to your desk, or shifting seats at a café — you don't even need to put it to sleep. Just tuck the keyboard under your arm, walk over, plug it into the next monitor, and pick up right where you left off. With Wi-Fi 7 support, syncing to the cloud is lightning fast. It's no longer "carrying a PC around" — it's a new sensation of "carrying your input interface around."

HP's pedigree as a keyboard maker is alive and well. The keys have a satisfying depth of travel, and the typing feel is sublime. On top of that, a built-in AI camera and sensors constantly monitor the user's posture, gently nudging you with a notification whenever you start to slouch or lean too close to the screen.
Security is fully covered too, with "HP Wolf Security" providing hardware-level protection. Even if it's stolen, GPS tracking and remote lock keep your data safe. This may well be the smartest answer yet to "BYOD" — bringing your personal PC into the office.

The direct sales price comes in at around 438,000 yen. That's a jaw-dropping price tag for a PC that doesn't even include a monitor — but this is a one-of-a-kind device with literally no competition.
Home, the office, a hotel on a business trip. As long as there's a monitor wherever you go, there's no need to lug around a heavy laptop. The HP EliteBoard G1a is a modern flying carpet, liberating workers from the very concept of place. You pull a cable from your pocket and casually connect the keyboard with a flourish. With that single gesture alone, you become the embodiment of the "future of work."
