Has anyone else noticed that navigation circle in the middle (the round button where you can select up, down, left or right) seems to be a bit loose on the bottom. I've noticed the top of mine seems securely glued/snapped/whatever but the bottom seems a bit loose. Almost needed to be pushed down a mm. before you're actually pushing the system button below it.

Perhaps I'm just OCD but I seem to have had a couple PDA products that have fallen apart in the past and I'm trying to predict.
