Who reads stickers? Read the sticker on the sun-visor of your car? Or the label on your beer? The drive should have a label itself, so the first time use it, you know. But what about when a 3yr old or a friend who moves the unit, not knowing about MS-being CHEAP AGAIN on their console.
The MS Demo guys should have anchored the console to booth if they didn't want people moving it... So yes, its MS fault on many levels... not to spend 10~20 cents on bumpers.
