I have had several tablets. Currently, I have a Windows 8.1 tablet, and an Android tablet.
I prefer Android for tablets. My Windows 8.1 tablet, being only a 10.1 inch screen, it's hard to hit the small buttons. Like just trying to close a window is a pain in the ass.
YMMV.
I'd recommend a 2 in 1, 12.5 inch or bigger.
Also beware of tablets that only have like 32 GB HDD and an SD card slot.
32 GB is very little space to run Windows.
Mine has a 32 GB HDD and I have a 64 GB SD card in it. No room for much. Tried to sell it, no one wants it.
