I know there are a million of these threads so I will apologize in advance. I've narrowed it down to a 13" MBA but I am unsure which version I should buy? My current early 2011 MBP has died after a great 5+ years. I need a computer pretty quickly right now. My local Apple store has the i5 version in stock but it looks like the i7 version will be available in two weeks, and of course at an additional cost. Am I going to regret going with the i5 model? Should I wait the two painful weeks for the i7 model?
