I'm new to the forum and have read many posts, but I do have a question. Do you guys think the lower end model 21.5 inch 3.06 I3 currently, if revamped, would it see sandy bridge or only medium grade models and up? I looking to purchase in a few days for my first mac.. I can only get the wife to agree to the lower end with no upgrades and debating what to do? If its not gonna change other than from I3 to possible I5 there isn't a major difference correct? I will be using for college work, photos nothing business worthy yet, home videos and amateur web design. I would be fine with current low end model and possibly a ext 1TB HD and maybe a RAM upgrade eventually right? Thoughts, comments????
