Obviously the high end one has its advantages: -90 GB more memory -Backlit keyboard (I believe low end MB doesn't have this, right?) -2.4 Ghz CPU vs 2.0 but it also comes at a price ($1499 vs $1250). What do you guys think is the better buy, both for value and long term. My usage involves light gaming (i.e. Spore and Puzzle Quest), streaming movies off Netflix, internet, Office programs, some stats programs, light video editing, music player, and nothing else really out of the ordinary. I want this machine to last me at least two years, ideally 3, so what would you guys recommend? I'm also tempted to upgrade to 4 GB of RAM if I went with the lower end MB, but would hold off on it if I got the higher end MB Are there more advantages than the 3 I listed? Are those even worth it?
