How can I tell when it's a good time to buy a MacBook Pro? I want to know if a particular date (for instance, October 1, 2010) is a good date to go ahead and buy a Macbook pro, or whether I should wait few months for new models to come out. How can I figure out whether a computer I buy will soon become obsolete?
See the comments to improve the question, but Macrumors' buyers' guide always has suggestions if now is a good time to buy.
