I'm always bummed about the power brick when I unbox one. It's funny because for most people it is a not issue. There are certainly more issues than the presence or otherwise of a power brick. Mind you, I kinda wish the PS3 phat had come with one - it may have reduced the size a little.
I just find it funny how this design basically screams less heat and noise yet everyone is complaining about the looks of it.
It really isn't a issue, you put it behind your TV and never have to touch it again.
