2 in our household as of yesterday. My son has the 16gb and I have the 32gb. Sitting at work with my Virgin Mobile miff figuring mine out. Have to learn about Logmein, which is cool, and I think I want Dropbox+docs to go for my documents...
I have three iPods, two iPhones, and one iPad all linked to one PC. No problems but, then again, I read the directions.
