I own a Surface Pro 2, and I generally dislike it. It makes for a terrible tablet, too big & heavy. Some people will say tsupersonic, try the Surface Pro 3. I have, and it's the same thing. You see once you get used to the iPad Air or a Nexus 7 or any other normal sized tablet, the Surface Pro 1/2/3 feel heavy and bloated.
The Surface Pro 2 also makes for a terrible laptop. The keyboard is expensive, has no travel, and don't get me started on the "trackpad." I know you don't have to buy the keyboard, and a cheaper BT keyboard would do just as well. However, all the marketing from Microsoft show the Type/Touch keyboards. There are also no Windows apps that are worth having, but thankfully it runs full blown Windows 8.1, so it's nice to have access to desktop apps. The device itself is very expensive as you add on the specs.
The best features of the Surface Pro 2 imo are the Wacom stylus and the OneNote software. These two work in harmony to make for one of the best drawing/note taking device out there.
If you just need a laptop, I would NOT recommend a Surface Pro <x>. If you just need a tablet, I would NOT recommend a Surface1/2 or Surface Pro <x>. It tries to be both, and doesn't do either well.
