Well maybe not a Pi or Rubix A10 (unless you add in Keyboard, mouse, and monitor)
A few days ago, my Nexus7 met an untimely end. Thursday I found its replacement at OfficeMax. They had a HP Stream 7 tablet on sale for $99.00 with Win 8.1 on it. Turns out it is NOT an WinRt system. So all the USB stuff works as it should for serial comms, USB to hard wire network (need that to run some stuff on CT systems and PACS/network checks) and USB to parallax products such as the C-3, Quickstart and USB proto-board. On the down side, it is useful to have at least a Bluetooth mouse (and maybe keyboard) to make life easier with the IDE, but it does all work. And the price is right. So far a real keeper as tools go. Just need to find a good X-sserer for it without having to resort to Exceed.
Ordnung ist das halbe Leben
I gave up on that half long ago.........
