I was going to get a Surface Pro until the reports of 4-5 hours battery life, instead I got a Samsung ATIV Atom tablet. I've had it for a couple of weeks now and I'm really liking Windows 8 in this form factor. I find myself switching to whatever form of input is best suited for the task I am performing, be it stylus, touch, mouse, virtual or physical keyboard.
I've had a few different Android tablets, going all the way back to the Gingerbread days and I currently have a tablet running Jelly Bean and I'm not looking back, the only thing I miss is my Unified Remote app.
