I'm up to my fifth Ipad 2 and all the ones I've gone through so far have a slight 'wiggle' to the volume switch. This becomes a little annoying when holding the device vertically and you're constantly able to 'play' with the volume switch (albeit slightly).. Has anyone else noticed this 'wiggly' volume switch? Can you guys possibly check yours? My father has one and his switch is rock solid yet coincidentally his mute switch is a bit loose. The volume wiggle I refer to is very slight, around a millimeter or possibly less, but still a bit annoying for a $500 device..
