It looks cool, but I've found the Steam Deck is the only portable computer that's versatile enough for me to actually use for all sorts of different stuff.

See I do have a use for this kind of thing, but not exactly. I have a few desktop towers and Raspberry Pi devices that sometimes due to upgrades or random acts of Zeus absolutely fail to boot up. I want some ability to connect a keyboard and a screen to these so I can see the actual boot screen. Normally for me this involves lugging the device to my office and connecting it to my office monitor and keyboard which is…
I _think_ you are describing (minus the screen) what a PiKVM and similar would give you.
I can confirm that getting a PiKVM has very much eliminated lugging around my server or a screen. Having some form of display input would be the one feature I would wish to add if given the choice. Not having HDMI-In, e.g. via capture card, makes sense in this form factor and power budget, but would make this an instant buy for me. I would really enjoy having a small, very portable device to debug things with.
I recently got linked to a CCTV tester [1] that at least handles the display part. Sadly it does not seem to have keyboard emulation. It might be possible to hack this in as this is an Android tablet at its core and the USB controller might support gadget mode.

#43Oh great! Another awesome looking cyberdeck that I want to own and will find absolutely no practical use for. I've added myself to the waitlist already.

I too have this use case troubleshooting headless computers around the house. I saw an ad for https://www.aurga.com and bought one for $84. It connects to an app on my Android phone as display, keyboard, and mouse. Minor discussion 7 months ago: https://news.ycombinator.com/item?id=38609526
Long ago I bought a mini keyboard + mouse combo for input; the custom wireless USB dongle edition I have (strongly preferred over Bluetooth when troubleshooting) is no longer for sale. https://amzn.com/dp/B00I5SW8MC

#44I wonder if simply adding one of these ESP with GSM builtin would turn this into a practical linux phone.
Unfortunately advertised battery life isn't practical. Though maybe with software enchantments it could get there.

#45I've been wanting to build my own handheld ever since I picked up a 3d printer so the last few months I've been checking these builds out. The blackberry keyboard is my favorite part of the build, definitely going to do the same for mine. Looks great with the casing.
I am working on the same kind of thing. For me the ideal keybaord/screen combination was the Keyboard Featherwing from Adafruit https://www.adafruit.com/product/4818 . Unfortunately, it is a discontinued product. I managed to snag one of the last ones, but I am reluctant to use something that I cannot get any more of.

#46This looks like a pretty cool device!
However, I was immediately curious about how the "dual battery" feature works. The IP5306 power-management IC seems to be designed only for a single battery, and as far as I can tell from the schematic[1], the two battery connectors are just directly connected to each other in parallel (across VBAT and GND).
This seems really sketchy. If you plug in two batteries that are not at the same state-of-charge, then you're going to get a very large current flowing from the higher-voltage battery to the lower-voltage one, probably significantly exceeding the batteries' rated current limits. At best this wastes a lot of power and generates a lot of heat, and at worst it could be a fire hazard.

#47Are there any compact 4G/5G boards which can be plugged into this for outside connectivity? Last I looked, these breakout boards were far too cumbersome.

#48It's nice, but I would use something with a bit more memory. An Orange Pi Zero 2W with 4GB maybe.
512MB nowadays is only practical if you don't use a GUI.

I have this exact same problem. I wonder how they solve this issue in datacenters and if that solution could apply to the home setting.

Logitech has similar devices. This isn't the one I own, but it's close.
