Hello, I just bought a rMBP and I'm looking whether to buy an Airport Time Capsule. Problem is that I don't understand what I can do with that. Can I use it only for time machine backup or also as an external wi-fi HDD? Basically I will buy it if I can do the following: 1) Make a partition such that I can use 500-800 GB for time machine backup and the remaining 2.2 - 2-5 Tb as external hard drive. 2) I'm able to access the hard drive everywhere (like a server) and also a win user is able to access it. Can I do it?
