I love my Surface RT (thanks to Microsoft and Build 2012) - but I plan on buying a Pro. Windows RT is just too limiting and doesn't work well in an enterprise environment.
With the Pro I can run pretty much anything, can even put Visual Studio 2012 on it, and it has the sweet stylus! I want to use it for hand written notes in OneNote, and for UX sketching.
The 1080p display is also sweet! Just like LAURA!
