I have always loved the concept of computers like this one.

I have a picocalc on order but I am aware I am unlikely to make such a restricted use platform work for me day to day.

I also have a GPD MicroPC 2, its just about perfect for me for actual travel usage as its just a small PC.

However I like the fact its based on a PI as it has a wide range of options for expansion and a large base of support to take it further if you need it to.
