I have an earlier Iconia W
For me - for _my_ use case it suits just fine.
I bought it because it's got an Atom CPU which meant full Windows (came with 8, was a crap upgrade journey to 8.1).
The main reason I wanted it was to slip it into a pocket when I travel for diving. It means I can plan dives and see the info from my dive computer without having to worry about taking a much bigger, more expensive laptop.
The screen is pants in any kind of bright light. It's not the fastest or the prettiest thing in the world either.
But it cost me less than a couple of hundred quid if I recall. It's been reliable and does what I need it to do without fuss or fluster.
I do realise this is a fairly unique use case but the point is that they are out there.
