I have two issues that are a little annoying.
No silver light or across the board flash. I felt like I was in the walled garden of a certain fruit company getting directed to download pages that mean nothing.
No local Dropbox sync. A bit shortsighted to have Sky Drive as the only local cloud sync in a world where many businesses share files on Dropbox. I think Box can be mapped as a network drive which is cool, but you have their limitations plus you need a network connection.
I like the Surface 2 specs, but I'm not touching it unless those issues are addressed or they have another refurb fire sale like this.
