I am liking the responses on the 11"...I'm intrigued.
One thing I did not note in my original post......
I do have a very stout windows pc but I consider it my "work" machine (I have a small business where I do CAD drawings daily). The reason for the Air would be to move my personal stuff off of the business machine and keep the 2 lives separate.
My personal uses other than what I mentioned in my original post would be banking/bill paying, syncing music and photos. Other than that, I'm a pretty simple user. The 11" is sounding better and better and hooking up to my 27" monitor (if ever needed) is a plug away.
How old are you and how are your eyes? As I head further into middle age, my MBA 11 is getting pretty hard on my eyes for text. My 2013 MBA purchase is going to be a 13 as my 2012 11 gives me headaches after prolonged use.
