For the love of god - just do yourself a favor, and get one with 64GB MINIMUM!, AND HDMI out - miracast is not a true 2nd display option, it lags way too much, and the fact that OEM's tried to rely on it is just plain idiotic.
That being said, I do love my Dell V8P, but it does have its issues - namingly, the stylus is horrendous, bordering on barely better than capacitive. It is really the little engine that could - I run full software on it, like AutoCAD, Sketchup, and Photoshop, and it runs them all flawlessly. Even 3d modeling in sketchup is smooth like butter - just don't expect to render on it. I am extremely happy with the performance on the Atom chipset, and will be excited to see what the i7 in the Surface Pro 3 is capable of in a month.
If I could do it over, I would get the Asus Note 8, with Wacom pen instead. For some reason, I was chomping at the bit to get rid of my Surface RT. I got the Dell V8P on launch from Walmart (only place selling it at the time), and apart from some charging port issues, and 2x's back and forth with Dell repairs, its been running great.
