Chinese manufacturers do tend to have room to move on samples and MOQs, I think it's really important for someone considering attempting hardware on the smaller scale have someone in China assist with interacting with the manufacturers. A big issue is the large amount of miscommunication which always seem to happen when western companies try to deal with manufacturers directly.
Like, a preferably low-cost / revenue-split consulting company for nonprofits and startups which gets the customers in contact with the Chinese HW/SW vendors and provides engineering (gongkai ecosystem) and especially cultural advice (translations!).
Also I'd prefer something much thicker to have more battery and a more powerful CPU. Thicker means easier to dissipate heat since air can circulate more.
Something much thicker would kind of defeat the purpose of being portable.
I believe what we have today is limited more by physical constraints (i.e. I can´t see myself writing code on a 7/8 screen, or typing comfortably on a keyboard that small) than actual technology.
Already, both on the Surface or a small footprint laptop (say, 11' Macbook Air), for me the experience is way worse than what you can get on a slightly larger laptop (13').
Batteries always takes room. I'd prefer a thicker laptop with more autonomy. I dont understand thinner laptops, especially plastic ones, since plastic doesnt seem to disperse heat very well.
Couldn't you use GSM modules [1] in your product right-away?

Also let me connect my phone to a monitor and keyboard and use the thing as my development platform. All in one.
Maybe a modular breakout board connectible to the IO port would be a better startup idea.
I've never programmed for mobile devices but are the operating systems open enough to let it be possible to write a drivers for these things?

I tried this. The problem is the HUGE amount of cash you have to put up up-front to just get devboards and datasheets. Also, while BT/WiFi licensing is pretty straight-forward, GSM licensing is not - and don't forget the licensing costs for the chips...
Furthermore, the more functionality you want to embed on your board (I intended on a ethernet+poe and a powerline/power supply board, linked via MII to the CPU), the more layers you will need on the board.
And RF engineering competence is a must both for functionality and for EM radiation compliance, and this is not cheap too.
Altogether a too small market.
