What do you all think is a better idea? I have a mid 2010 15-inch 2.53 GHz Intel Core i5 running Lion, in great condition, and a warranty until 2013. The problem is that it just doesn't match my needs. I multitask like a maniac. And now I'm getting into music and video production. But even without that, I find I am eating up my 500 GB harddrive quick and my processor seems to be overwhelmed. I've deleted large files to make it run better, but I am starting to think I just need more power. Since my AppleCare goes until 2013, wouldn't this be a good sell? Then I could drop another 1.5 grand on a new 15 inch. That would set me for three years easily. OR, should I buy more RAM and double my 4GB to 8 GB? Will that be a cheaper approach? Will I have a similar outcome, namely, a faster computer? Thanks!
