I upgraded to the Nokia 5300 XpressMusic after three years of service with TMobile and a Motorola V300. Comparing the Nokia 5300 to the Motorola I noticed one huge difference right out of the box: Nokia is made of very lightweight plasic. This wasn't much of an issue until I went to change the SIM card out of the Motorola and put it into the Nokia. While I didn't break the back cover of the Nokia, it was a fear throughout the process. It's a very thin cover and since they are relatively cheap, I think I'll buy an extra one to have on hand just in case. I think the case on the Nokia is a bit on the delicate side, and you may want to consider a hard pastic cover (as sold on Amazon by Bargain Cell).
