I think this is a common issue, but is this just a software/firmware issue or should I be concerned about a hardware issue?
I have two days left if I want to return this thing, and you can imagine that I'm wrestling with the knowledge that new Macs are just over the horizon.
Technically, it pretty much does suit my needs. For anything more intensive I would need a desktop anyways. As for the new machines, I will benefit from the graphics upgrade, but no, I don't think it will change my life. Honestly, I'd prefer to wait for the first update, maybe next spring.
It happened the first time I used that USB port, but has been normal since. I think I'm probably being overly worried. The fact that it was an open box made me a little paranoid. My first thought was: oh, must have been returned because of a bad USB port.
Hopefully it was just a passing abnormality.
