Dude, you're on a tech support forum, all you're going to see is complaints about issues. (go check out Apple's support forums for example)
I've had mine a few months, recently swapped out the main board and it hasn't been too long.
False, defects happen, but AFAIK very few will fail within a year.
As RumoredNow said, don't worry about the complaints until you experience a problem yourself. I've had mine for 9 months without any issue at all...It's been rock solid.
I do experience some heat while charging with the supplied charger, or on the wireless plate, but it's never been an issue and not something I'm concerned about.
