Ok, yes. Time Capsule is Airport Extreme with a built in drive. USB for printers and hard drives. Don't believe it supports optical drives. Lots of people make wireless printers, I like my brother MFC-820CW (the w is for wireless). I hang a laserjet 5 off my airport express and have the brother wireless. I use apple bluetooth keyboard and mighty mouse, and like them a lot. I like the new chicklet keyboards too, but my bluetooth keyboard is the old one. I believe you can use the time capsule both for nas storage and backups, but I have the extreme, not the time capsule.
