I want it!

But the question to me is, how reliable is it?

If I turn it on, can I resume working on my script or taking notes, or do I have to sometimes start with debugging the keyboard driver with a touch screen?

(I am burned a bit by pinephone and co. who never evolved beyond tinker toy)

How well does said laptop handle google maps or a youtube live stream with chat? 1080p60fps video?

Video is accelerated and works fine. Google maps is useable (I just tested it) but not great. It's not too much worse than it is on my MUCH faster M3 Macbook, though. I think I just don't like Google maps. Apple maps works better on both devices. I'm not going to pretend it's not a comparatively slow computer, but the most it really affects is application launch. Starting Firefox or Chrome is pretty bad: five to ten…

Thank you, that gives a good performance estimation of what to expect and I still like it.

Thank you for this, It'll help people make up their mind.

Tangential: I'm looking for a handheld Linux computer that's the approximate size and shape of a GameBoy Advance SP, but with a QWERTY keyboard and wifi. The old Zipit Z-2 would've been perfect. All it needs to run is git and Emacs/org-mode. It's a surprisingly hard form factor to shop for—anyone have any recommendations?

I have a Planet Computers Gemini, which is a reinterpretation of the Psion Series 5, running Android but you can also install Linux. They have new models since, but I've heard reports the company is not honoring orders, so caveat emptor. Another option would be one of the GPD Pocket mini-laptops, they actually ship with Ubuntu. I'd gotten one of the older models, but the screen was just too small for my tired eyes: h…

The Gemini build quality also left a lot to be desired. As well as the software. I liked the idea but I sold it in the end.

Be sure to put those connectors through adequate stress testing. I’ve had several products that use a similar design (Garmin watch, Bluetooth headset) and I’ve been disappointed to find that the connector wears out with time.

Are pogo pins the gold standard for data across the most (dis)connect cycles? Could any hardware engineer chime in?

Pogo pins should handle tons of connections yes. At work we used these for board testing through test points ("bed of nails") and i never heard of the pogo pins wearing out.

These were pretty long pogo pins though. They wouldn't fit in this thing.

If you want something similar to this RIGHT NOW that has thousands of available parts and millions of users, see https://m5stack.com/

Disclaimer: Founder here M5 is based on ESP32 so it is microcontroller based so you are limited to things a MCU can do. But yea I love the M5 platform, funnily I am here at CES and met the Founder of M5 just yesterday!

Your disclaimer made it seem like you are the founder of M5. Luckily the context in the second sentence made it a bit more clear.

Not sure why I would want a handheld computer. But I still need a phone (calling, SMS) occasionally. So I use that also for browsing and messaging, too. GNU/Linux would be a great plus. What are my realistic alternatives? Realistic meaning not a huge amount of work and/or unreliable/buggy system.

If you just want calling, sms, browsing and messaging, and some amount of GNU/Linux, your main options are: 1) Any officially supported sailfish OS device ( https://shop.jolla.com/ - which includes their licensed and officially blessed version for older sony xperia services) 2) Any ubuntu touch supported devices: https://devices.ubuntu-touch.io/promoted/ Would be very stable... And good enough for daily use.. But hon…

1) Yes, I am a Sailfish user. I have been quite happy with the older generation hardware up to Xperia X. From what I read the newer generations have been more problematic. Yeah, after having skipped some I ordered the bleeding edge Reeder and was bitten by the disk encryption bug. Have been busy recently, should finally check what is the repair situation for that...

Android: After my Xpdria X HW got unusable as a daily phone I have used Android (mostly without Google). But general administration seems to be a lot of work a lot to learn. In GNU/Linux I know what to do without any extra effort. Time is limited...

A phone with Termux recently had the USB port go bust. I could neither charge it nor use ADB to back it up. But I was able to SSH into my desktop and back up the important files (voice notes, photos) via scp with the clock ticking at 3% charge and dropping. Very impressive and honestly being able to install ncdu on the phone to quickly find large, important files was a revelation in the usability of both bash and And…

Yeah, I have installed Termux. And learned to hard way that you need to install extra packages e.g. to access the clipboard.

I also read something about some turmoil in the community with unmaintained packages or what it was. Yet more time needed to really understand the situation.

At the expense of more software dev and a bluetooth module, It would've been more extensible and versatile if it had just used BT for input (HID) and GPIO rather than creating yet another proprietary connector and forbidding the use of GPIO and a keyboard simultaneously. Why not integrate the most popular one and use BT for the rest? Great, we've re-invented what already exists. Sigh.

Having a micro sized detachable BT keyboard would be amazing, but it would still need to charge somehow.

It seems like the whole point is that it's one integrated piece you can slip in a pocket, not a collection of hacker gadgets with separate chargers and USB cables you have to be careful about.

Founder here, thank you for this note we will build a jig to test this out and share results on our docs. One of the things we have done to reduce wear over time is that the spring contact is on the device and we expose a very small contact surface from the housing. Check this - https://ibb.co/xqm3z3W

I suspect the actual reason USB-C does so well is the redundancy.

With so many connectors, it seems like you could do 3 or 4x redundant connectors for something simple like I2C and power or maybe even USB2.0.

Seems like pogo pins are pretty top notch reliable by themselves though.
