You'll replace and/or fix hardware issues?

Fair enough, I'm probably making up my own use scenario here.
What would be your use scenario for it? Genuinely curious as to what you'd use it for and how much use you'd get out of it. Especially when primarily using a full OS.

I really liked my past keyboard smartphones, I think I've owned 3. With one probably still being the favourite phone I've ever owned - Sony Ericsson Xperia X1.

When I had my G1, I would easily jot down things when they occurred to me, and could admin servers without half the screen being obscured - I can't do those with current devices.

What I've never been able to do is quickly prototype ideas to check their feasibility, or simply run scripts and applications written in any language I wanted.

I noticed that Planet Computers (the company behind the Gemini/Cosmo) are planning a 5G slider device for next year - likely to be popular amongst people who don't like clamshell but still want a keyboard...

Indiegogo. Hmmm.

Got one of those dumb arse curved edge screens though. :&

Still nice to see the successful proliferation of these devices, proving there is a market for them.
