Ask Slashdot: Is There A Screen-Less, Keyboard-Less, Battery-Powered Computer?

Long-time Slashdot reader Wycliffe writes: So I have a travel keyboard that I love. I can carry my OS on a USB flash drive. There are several options for portable battery powered monitors. The only thing I'm missing to have a completely modular laptop is the CPU/MB/RAM... I can get a laptop but it seems silly to carry around a laptop with a keyboard when I never use the keyboard. I don't need a long battery life, if I need more than an hour then I can find somewhere to plug it in...

I've thought about buying a small box like a Zotac and trying to replace the hard drive with a battery -- but does anything like this already exist...? Also, are there any systems like this with decent specs? Most stuff I see like the Intel Compute Stick are horribly underpowered compared to a decent laptop.

The original submission drew some interesting discussion. Another option is "a good x86/x64 tablet that I can install Linux on" -- especially with a decent processor -- or "laptop-like systems that got rid of the screen entirely... I just need the travel CPU part without the added weight of a second keyboard and monitor." So leave your best suggestions in the comments. Is there a good, lightweight computer that's battery-powered without a screen or a keyboard?

      If one was going the DIY-way, I'd rather recommend Up^2. It's an actual x86-board, so it can run all the usual x86-stuff, there's a proper mPCI-E - slot for mSATA- and/or NVMe-drives or whatever mPCI-E card you may want to use, an M.2 2230 E-key for real, proper WiFi-cards, a SATA-connector, 3x USB3.0 (and a couple USB2.0-ports via a pin-header), a lot, lot more capable GPU than Raspberry Pi's one, built-in eMMC (the top-end model has a 128GB one) and so on.

      The thing is, an RPi makes for a really crappy desktop-experience. The Up^2 is significantly more expensive, but it's also significantly more capable and much better suited for desktop-use.

      The stuff that everyone wants to use is a combination of a .exe and a load of .dlls. The .exe will be x86. Any bundled .dlls will be x86. The system .dlls (where a lot of apps spend a lot of their processor time, doing things like text layout and rendering, animations, and so on) will all be native. There's a penalty for calling between the two worlds, but only a few dozen instructions.

    Kangaroo Mobile Mini PC
    Intel x5 z8500, internal battery
    I have the smaller memory model and it gets hot but seems to be OK, the Plus model with more memory apparently has some heat issues according to the reviews.
    I have Fedora 25 on it and I read somewhere it doesn't use the GPU for graphics, but it works fine for me in low demand uses.
    The lack of GPU use might also be why I don't have the heat issues.
    I can't get the sound out of the HDMI feed, but I think that will work eventually when the kernel gets enhanced.

      I haven't heard of these Kangaroo PCs before, but I like the idea. Or, what I'd really like is something that's a mix between this and the Samsung DeX dock, or Microsoft's continuum. Plus Thunderbolt 3.

      Like, take one of these Kangaroo PCs, and add a Thunderbolt port, cellular radio, and a touchscreen, and give it a UI on the embedded screen that works for a small screen. Or, if you approach it from the other direction, give a smart phone a Thunderbolt port, develop docks for it, and allow it to operate as a full computer when docked.

      Of course, someone is going to ask, "Why are you talking about Thunderbolt? A lot of phones have USB-C." The nice thing about Thunderbolt is that it provides better access to the internal bus, allowing external devices to act more like internal devices. With Thunderbolt, you'd be in a better position to have docks include additional power and features. You could do things like have a discrete graphics chipset embedded into the dock, that would allow a small underpowered computer to play games with better performance when docked.

    It's a confusing summary based on an earlier submission.

    Inquisitor already has a substantial emotional investment in a fancy keyboard and a battery powered monitor. Wants a machine to plug these into. Seems to want a 'real' computer rather than a phone.

    Attachment is to the monitor, or would have solved this by trading it in for an Android tablet (Nexus 9/Pixel C) with a kickstand - there are projects on xda for porting arch or ubuntu to these things.
