Hi all. It's been a while since I posted anything. Much has changed since you helped me deciding to buy a 17" MBP, and I need some advice. I bought the sandy bridge model when it first got released back in February. I upgraded to anti glare and 128 GB SSD (through apple). After finishing my first degree in engineering, I'm now starting to study for a masters degree in technology management. As it turns out, I don't really need a quad core portable computer for this. I'm now, as the title indicates, considering selling my MBP before it loses more value (I bought it with student discount so it wont be a big loss, maybe on the contrary) and get the coming 13" MBA. I don't game anymore, but I like to edit photos once in a while. I have a 24" monitor in my room though. The main reason I'm considering this is because I'm going to the states next spring for three months. Then it would be nice to have a light computer. If I regret my choice I guess I could buy a new 17" while being there (much cheaper than in my country). What do you think?
