Just think, it was only 2 years ago, and the PC I was using only had a 20GB HDD. It still had a good 10GB left in her before we sent her to the farm (or at least that's where my parents said she went).
I'm wary of 3rd party products. I bought my brother a car charger for his nano and it roasted it. Fortunately, iPod has good customer service and it went from my house to China and back again in 4 days or so.
