Just wanted to share my experience with the Time Capsule. I purchased a 500GB Time Capsule and replaced the drive with a 1TB WD Green 32MB buffer drive that I had. It works perfectly and was a breeze to set up. I'm loving it so far. I haven't experienced any issues or problem with wireless connectivity, file sharing with a PC, and TM backups. I think it's a good product if you're in the market for a backup, file sharing, and wireless router device.
