Two questions... I'm trying to decide if it's worth $150 to upgrade to the i7? The most intensive CPU work I do would involve Microsoft Excel that involves editing 60,00 rows. If i do any video editing it's for home movies. I will run boot camp to play some old pc games and not expecting a "gaming pc" out of the MBA. I've heard it's pointless to get an i7 unless the software I have utilizes it. Is this true?
