I am looking to buy a MBP in the next couple of weeks as the backtoschool sale will be on soon here and would like to save a couple of bucks and I think the current generation would suit my needs. I am just a basic user and mainly do word processing tasks/itunes/surf net/parallels running windows 7 for my statistics program. One thing I do is multitask and have a million things open at once. Would it be worth to upgrade to 8gb of ram? http://www.streetwise.com.au/memory_results.php?mem_id=56& would this do the trick if I bought the standard 4gb? Secondly, am I better off with the mid range and upgrading the ram or going the 2.8 15"
