I have had several BB's - a 7100i on Nextel, an 8800, an 8310 Curve, and now an 8900 - last three on AT&T... While the features of the 8900 are great, especially the WiFi, it is the worst of the bunch for physical integrity. Compared to the others, it is quite flimsy. Out of the box the keyboard was loose and the trackball worked erratically because it is not mounted securely like the others. The shiny chrome scratches very easily during normal use. After three months, it fell off my desk and the LCD cracked even though it was in a gel skin that cushioned it some. Because it was unlocked (TMobile used on AT&T) the warranty will not be honored by anyone, either. That was the last straw for me. I went back to my 10 month old 8310, which is still solid, looks good and works very well. What is supposed to be the latest and greatest is not necessarily that way.
