I 'd like some advice about the new MacbookPro. I decided to bite the bullet and purchase a new MacbookPro. Best Buy is selling the older model (which was just returned) at a discount. It is open box -- the salesperson claimed that the person who bought the computer returned it within the two-week time period to get the new Macbook Pro model. It seems new -- no surface damage, and the power cord still has its plastic wrapping around it. This is the 15" MacbookPro with a 2.4 GHz Intel Core i5 processor, 4GB of 1066 MHz SDRAM, 320 GB hard drive -- and I can get it at Best Buy for $1315. The new, comparable Macbook Pro (15") has a 2.0 GHz quad-core Intel Core i7 processor, 4GB 1333 MHz SDRAM, and a 500 GB hard drive. I could buy this machine for $1699 with my educator's discount. My question is: Is it worth it to pay an extra $400 to get the new model? I mostly use the Adobe creative suite, edit family movies using iMovie (but hope to learn Final Cut), store and edit lots of photos and use WordPress and watch YouTube videos on a daily basis. Thanks for your advice!
