I'm happy with mine, even with random reboots. I don't think there's been a reboot that's caused me problems. Usually, I just notice that it's rebooted/rebooting, and hasn't drained the battery. So, to me it's a minor inconvenience.
Depending on the price, I'd buy it again. Now I'd weigh it against the current model and may spend a little more on the newest model.
