I needed a Windows tablet, wasn't expecting too much initially but it's turned into a very pretty good experience. Cheap Acer W500 but put a larger SSD in it. In the office I access it over the network via a remote desktop connection. I use Microsoft"s cloud to keep OneNote in synch across several machines including the tablet, also Dropbox and Evernote.
The voice and handwriting recognition works extremely well. I take notes either on-screen or with a digital pen, and have a folding Bluetooth keyboard.
I've got the Android version too, and I did have an iPad for a short while.
