Win 8.1 tablets are pretty nice if you wanna do stuff you can only do on Windows PCs like play VNs and whatnot, or you actually wanna get some work done.
The Dell Venue 8 Pro is pretty cheap (at least over here in the States, I can pick one up for you if it would be cheaper from the M$ store, hehe)
Also look at Lenovo's new 8" tablet too which has a 1200p screen IIRC. And don't forget to look at the ASUS Transformer Book T100 as well. :3
Windows 8 is weird. It's a terrible laptop operating system, and a terrible tablet operating system.
As I've mentioned before, I have a Sony Vaio Duo 11, which is a slider ultra-portable 11.6" Windows 8 machine. It's too heavy and operates too hot to be used as a proper tablet, and the screen and keyboard is too small to type comfortably. The battery life is average for PC standards (3 hours of use), but way behind that of Android tablets. I intended to get it as a substitute for my old 15.6" laptop and my Asus eee Pad Slider SL101 (which was a terrific tablet with a very nice keyboard for Android tablet standards), so I wouldn't have to carry two devices with me all the time.
Big mistake.
Now I have something that's not quite a Windows laptop, but also not quite a tablet either, whilst wishing that I had spent that $2000 on a laptop and an Android tablet instead, possibly even with money to spare!
Also, Windows 8/8.1 has terrible backwards compatibility with XP based VNs. I've practically stopped playing Clannad (and stopped reading manga online) because of it.
TL;DR: Don't get a hybrid Windows 8 machine unless you're fully satisfied with what you're dealing with. Most likely, getting a Windows laptop and an Android tablet as two separate devices will get the job done much quicker, better, and cheaper.
