Moving the console during use is retarded, do you move your computer aswell? Hell, you can damage your harddrive if you tip the tower over when it loads(or even move it, slightly). And who have it standing upright anyway(the 360, that is)? Just because it's often is pictured in that state doesn't mean it's a good idea (infact, it's a stupid idea). And WHY would you move it anyway?! People are think in the head, for sure, I'm beyond words...
And last but not least, who the FUCK place it where you can accidently tip it over? Really? I have friends with pets/childern(and who play Rockband /w drums & guitar) who run around and they never had a problem with this... why? Because they didn't place the 300$ hardware on the middle of the floor! Hell, I keep almost all of my electronics out hands reach(or feet) except the PC monitor and the TV. I have to leave my seat to change discs anyway, so I don't really see this as a problem.
People who sees this as a problem are stupid or at best, clumsy... no, sorry, just thick in the head.
Also. Game installs.
