I got cold sweats.
My brand new iPod Nano froze today. I have had it only 5 days. I was not listening to it; it was paused, on "hold", ini my (ample) pocket. I did not bump it, not shook it, nor bend it. I have been very gentle with it. But this afternoon, going out of Starbucks, I pulled it out of my pocket, and it was not responsive. The screen was blank (nothing on it whatsoever, as if the battery was out). I looked on the web, and found this nice site. I finally revived it after 3 or 4 hold-on/hold-off then reboot. It's ok now. I hope this won't happen again anytime soon.
Update from july 10: it seems to have fixed itself now. Go figure.
