Hey do you guys think the macbook air can handle large excel sheets, intensive formulas/sheets, and large VBA workbooks? I do a lot of financial modeling and was curious if the processor and amount of ram can handle huge excel workbook with extensive calculations? Other than that I don't really use my laptop for anything but web browsing and email... just have XP setup thru boot-camp/fusion... Just wondering if this can handle hard core excel stuff.... if not I'm afraid I have to go back to the bulky MBP.... I really could use any advice possible you guys can offer... I'm brand new with a mac, been a windows user my whole life and switched over last month.
