Hi, I'm considering whether to buy the low-end or the high-end of 15-inch Macbook pro. Can someone give me some suggestions please? Here is how I'll be using it most of the time. - web-browsing, emailing, chatting over skype - listening to music, watching DVD - writing some documents as word or excel I guess the low-end 15' is more than enough for the tasks above, but I may also play some games (if I can find some good Mac games, such as the strategy games) and run some other fun applications. Do you think I should get the high-end instead? I think the spec of the high-end should allow me to use it for a longer time without having to upgrade, but it also depends on whether the machine can actually last long before various problems show up that would force me to get a new one. Thanks.
