Now that I've started buying TV shows on iTunes I've begun to think about changing how I back things up. Buying a Time Capsule seems like a simple solution, if expensive. I have two questions: 1. Can you use it as both a Time Machine and a hard drive? My only computer is a MacBook Pro with 256GB of SSD, so I'm going to need to back up iTunes purchases manually (I presume?). 2. It's a relatively old device. Are the WIFI features still state-of-the-art? Will it perform better than my brand new Virgin SuperHub?
