Great, Microsoft has a disclaimer that says don't move the console while its on and there is a disc inside. Supercool. The fact still remains that the cd rom drive in the thing is a piece of garbage.
This doesn't happen on my Wii. I can tilt it, move it around etc. and not have any problems. Not to say that there aren't limits with that, but, you can move the thing without scratching your disc.
Sure, if i was single and it was conveniant to put my xbox into some sort of entertainment center where it would be off the floor and not likely to get bumped. But, unfortunately, if you have a family with small kids, the tv your wife lets you plug your xbox into doesn't really have any provisions for a protected enclosure for your xbox and hey, lets be honest, everybody forgets - or thinks - hey, i can plug this accessory in with it on, i'll just be careful, then next thing you know - whoops - there goes 60 bucks.
Its a video game. It should have some tolerance to "real world" conditions. Dogs, kids, etc. Not saying you should be able to drop kick it and shake it, but, there should be some forgiveness.
