Not sure if this is the right forum, if not please move it! I can't find any info on this on Apple's site, either. I'm thinking of getting the new MacBook Air, and trading in my iPad 10.5 against it. I think I may need 16GB RAM, but going to try out the 8GB first, and then return after using it for a week or two and order the 16GB online (as you can't do upgrades in store). What happens when I go to return it as they have given me credit for the iPad 10.5? Do they just refund the full value of the MBA? Thanks in advance.
