I’m not sure where I heard it, but I love the saying that says if you want to buy a computer, wait a week. There will never be a good time to buy technology as it will always get “better” and become cheaper. I had been planning on purchasing a new MacBook Pro after I paid my taxes, my my dog’s root canal put that on hold. Today, I’m sort of glad I waited and will be waiting for the new round of MacBook Pros to come out (whenever that is) because Fujitsu announced a 320 GB 7200 RPM portable drives. I always get my portable machines with 7200 RPM drives as I like the extra speed for development. As of now, the largest you can get (at least from Apple in a build to order configuration) is 200 GB for a 7200 RPM drive. Hopefully Apple makes the Fujitsu an option or other vendors increase capacity for the 7200 RPM drives.
Waiting, however, will be hard as my current machine is approaching 2 years old which is an eternity in computer time.
