Describe what you are doing (encoding video, playing games, etc) that is causing it to "overheat and throttle" all the time.
General use. You don't even need to be doing anything special with it to start it's micro-stutter routine.
Can you quantify "piss-poor" a little better?
2 hours. Maybe 2.5 if I crank the brightness way down.
"Overrated" is a completely subjective statement. Can you be more specific?
It's not significantly better or worse at performing general tasks, but it's touted as being significantly better at all tasks. It's overrated.
Did you ever take it to Apple while under warranty to address the overheating/battery-life concerns?
They can't do anything with it because it's a defect in the 2nd generation airs. Apple didn't give two shits though, they already had people's money. No fix was ever issued for those affected. I will never spend that kind of money on Apple's trash again.
