Surface Pro for editing?

Hey guys,

I was wondering if anyone had any experience using the Surface Pro for photo editing. I am considering a new computer and I really like the idea of being mobile with a stylus and editing photos that way. I mostly use Lightroom and Photoshop at the moment and was wondering how well those might translate with a pen input. I worry that there aren't too many programs that can fully utilize the stylus input the way I am planning to use it. I also have some reservations about the screen size as well. 11 inches seems a little tight for some of the controls menus in those programs.

Does anyone have experience doing this? Let me know how you liked it and if any of my concerns are valid.
