DigitalTrends put the Apple TV through a series of tests to determine how hot it gets while playing content. They even used an infrared camera!
A few days ago, I bought and reviewed one of Apple's brand new, ultra-popular Apple TV entertainment systems. I wrote an exhaustive nine page review (yes, 9 pages!) and found plenty of positive things to say about the Apple TV. I also made sure to point out the negatives so as to not give a biased or intentionally one-sided report.
There were two major issues I had with the Apple TV when I first tested it. The primary issue is the somewhat disappointing picture quality when using HDMI cables. This was probably the most baffling because HDMI is considered superior to component cables; component cables being the only other way to connect your Apple TV to a television..
