I may try it on one of our tablets soon if I get a chance. That'll definitely be a real test. If we can update from XP to 10 for $20, I'll probably do it. Linux runs great on these, however the support for the work software we use in Linux is very limited and slow. The issue isn't with Linux, its with the software company, but its an issue all the same. I'd much rather use Linux, but for $20, I'll definitely consider it if Win10 ends up working as well as its supposed to.
I don't know if thats going to be the case with XP/Win7 though - I think they were saying its only going to be Win8 but who knows as of yet.
