I have an original Apple TV and the thing sucks so bad that it is virtually useless. Out of all the time I have owned it, I bet I have used the thing three times. Talk about an epic fail of a product. When Apple announced the new Apple TV, I was not interested even a bit in the thing considering how bad the first product was. There are a lot of people excited about the new device though so maybe it won't suck as bad as the original.
If you are interested in the new Apple TV and would like to see what the thing is hiding inside its black case, iFixit has ripped one apart already. The new version is much smaller than the original and comes with a remote control. Should you ever want to repair your device on your own, this tear down could come in handy.
