also once i had the air i never used my ipad. so get the air first you may not want ipad after.
I currently have a 3 year old white macbook and am thinking about upgrading to a macbook air. I also have an ipad and am worried that the two would overlap. The apple store talked me out of buying a MBA (because of that reason) last time I went in but I am still in love with the MBA. Would I be better off with a MBP?
