I'm really enjoying my surface 2. Connects easily to work email and calendar, full office installed for productivity (one note is excellent for note taking in meetings), offers a microSD slot for expansion and a full USB 3.0 port, and the web from the desktop version of IE is just like using the web on a full laptop or desktop--no "this video isn't available on your device" any more. It's a nice slice of freedom in that regard. Kickstand is a much appreciated built in, too.
All I'm currently missing right now is a being able to install my company's VPN client to remote into my work pc.
I love Android for my phone, but for a tablet, the surface 2 is much better for all-around use, for me, than my android tablets have ever been.
I haven't tested very many downloaded videos on this yet, but the one or two I have tried played without a hitch.
Only negative I've found so far is the lack of a GPS chip, so no location-based features, but I have my phone for all of that.
The type cover 2 is a great pairing with the surface 2 and the ability to "rip" it off and tuck it in the seat pocket on the plane if you really need to use it in it's tablet form gate-to-gate.
If I had wanted to spend the money, I probably would have bought a surface 2 pro, especially after the battery life gains shown by Anandtech after the latest update, but I didn't need or want a full-fledged windows laptop; I already have my desktop to keep me satisfied in that regard.
