I've got to say that this thread highlights the fact that certain BB 8900 owners seem to be among the most anally retentive people on earth!
I've read threads about loose back covers, wobbly keyboards etc.
I had to return my 8900 as it had a software bug that gave me half a screen of one app, and half a screen of another, which i think is a reasonable reason to ask for a swap.
My new phone has a keyboard that moves (as did my last one), and also a cover which has a small degree of movement. However, it works great and has made me a very happy 8900 owner!
Please guys, get a grip. There are many many very serious issues in our world today. I have to say it is embarrassing to read some of the 'issues' highlighted on this board.
A different perspective: my 15 year old son has an ipod Nano. It is battered with scratches and digs all over. However, it looks pretty cool in a distressed 'done a tour of duty' sort of way. It works 100% correctly. His phone is the same, and also works perfectly. 8900 OCDers, read this paragraph and consider it therapy
