What do you think of the Microsoft surface 2 tablet?

It's expensive! The Microsoft surface 2 32GB version costs $389.99

It runs on Windows RT - which is still incompatible with legacy programs

The same 32GB tablet by HP Slate costs just $99.99

It runs on Windows 8.1 OS and has many apps available on the App store

The best tablet if you like windows

Big difference between Surface 2 and Surface Pro 2. The first runs Windows RT - it can only load apps from the Windows Store, but it does come with Office 2013 built in.
The Pro version (there's also a Pro 3 improved device available now) runs normal Windows 8.1, and can load apps from anywhere, but doesn't include Office.

There's quite a range of 10" Windows tablets available now… From many different players (Lenovo, HP, Dell, etc). The Surface is good for screen solidity, screen resolution, and the fact that it is only a tablet (running RT), and not trying to be a laptop as well.
Personally, I prefer the Pro 3, that IS a laptop as well as a tablet!

Honestly, for about the same price, a MacBook AIR is a better choice.

Why?

Then, if you also need Windows 8.1, OS X's BootCamp App allows you to install and run a legal Windows 8.1 (<> $99) in a dual boot configuration.
