Hi folks, I think it might be reaching the time to upgrade my laptop. My 2009 Core 2 Duo 15" MacBook Pro no longer reads DVDs, has a few scuffs on the screen and what looks like corrosion on the edges of the top case, and the trackpad has stopped registering clicks about 70% of the time when I click it. I could keep it for a while longer - I've had it for two years and three months (from new), and I know there's probably a redesigned model coming out next year - but what would you do? Would you upgrade just now? I'm thinking maybe I should upgrade before the new model comes out - the current line is a very mature product, whereas I've been very unlucky with brand new releases from Apple. Anyway, what are your thoughts?
