I may just end up waiting on all this to see if Microsoft updates the Surface line with Haswells. Perhaps they'll also address the kick-stand issue. Though with their recent financials maybe the Surface line isn't going to get refreshed?
EDIT: Should also mention I'm right there with you on MBA being the best value. The Surface's main appeal to me is its tablet form factor - I like tablets and have lots of fun using iPads, but an iPad just can't replace a laptop for me and the last thing I need in my life is another device! 2-in-1 would be great.
