Hi all, First post, but I've done a lot of reading on the forums and reference sites, so not completely new. Sorry to add to the list of "which should I buy?" threads, but I'm having trouble deciding. I currently use a 2008 MBP (which replaced a 2005 iBook). I'm not a "power user" however you define it, but I do tend to use up my laptops. For example, my current MBP hasn't been able to load more than 2-3 Safari tabs simultaneously for about 10 months, and having Word or Excel open at the same time as Safari has also been a struggle for a while. (Yes, it's in bad shape -- I was waiting for the 2011 update.) Basically, I want performance and durability like anybody else, and given the three-year period that I'll hopefully use the computer, let's say that a price variation (within $500-$750) doesn't matter that much. I want a 15" of some sort. Should I go for a refurbished 2010 or one of the new ones? I'm not techie, but I'm willing to explore adding an SSD if say, buying a refurbished and adding an SSD might be the best. What specs should I be looking at? Much appreciate any and all of your guys' thoughts. I want to learn more about this stuff. Thanks!
