Hello, I have a 4 Gig Ipod Mini, I bought it in August of 2005, and a few months later the Nano, and Video came out. I was dissapointed I had no idea they were coming. I am ready for an upgrde to a new iPod, but I dont want the same thign to happen. So how long do you guys suggest I wait for the next gen to come out, in the past hasn't it been atleast once a year?
