Hi, I am looking at getting the new Time Capsule, but have some things I want to check before I buy it. I'm going to use it for time machine to back up my macbook air, but also want to use it to store videos, music, etc so that the 2 windows PC's in the house can access them too. I believe this is possible in principal, but read mixed things online about the windows machines being able to access the media files. Do they just see it and can access them fine? Also, does it connect to an existing wifi network and act as a wifi extender, like the airport express does? I'm with Sky in the UK and you have to use their router, so I'm not in a position to just replace that with the Time Capsule. Cheers for any help.
