My wife currently has a 08-09 MBP 17". It has been a great machine, but I think the 17" is going to be a bear to carry around (which she will be doing more often for the next year). I am between the 13" MBA or the 15" MBP. The biggest concern I have with the MBA, is the speed of the processor to run Parallels, browser, mail, etc. While I think the 15" is going to be a bit overkill for what she is going to use it for. Anyone have suggestion? I would be looking at this for the MBA http://www.amazon.com/Apple-MacBook...HZP4/ref=sr_1_2?ie=UTF8&qid=1313429856&sr=8-2 OR This for the MBP http://www.amazon.com/Apple-MacBook...p?s=electronics&ie=UTF8&qid=1313417492&sr=1-2 Thanks!
