Could anyone give me a rundown on exactly the differences between buying Time Capsule and buying an Airport Extreme and a 500 GB/1 TB hard drive? With recent developments, I'm thinking of buying one or the other, but I want to know the best value. I'd like comparisons of cost, speed, ease-of-use, compatibility (Windows, Mac, Linux), ability to use from more than one computer, ability to use multiple partitions (say, one for TM and others for plain storage), expandability, etc... anything you can think of. I have a feeling that Time Capsule is the better buy (except for expandability and ability to hook it up as a USB drive directly to the computer). Thanks!
