so i just purchased the newest high end 13" MBP from bestbuy. did i make the right decision? should have i gotten the low end 15"? i dont do gaming or do and type of video. just need internet, photos, and listening to music. its my first mac EVER. also should have i waited til summer to get a new mbp? since the new os lion will be announced and will be able to get a free upgrade or discounted? or will i still be able to get a discounted upgrade price?
