I need a new cell and these are the ones i can choose from

PalmOne Treo 650 Cingular

Samsung D407

Sony Ericsson W300i

Motorola SLVR L2

from these four and no other. is there anything wrong with the treo? i like the fact that it has the keypad layout... i dont know much more about the other ones.... maybe if u have it can you give me some pro's and con's? thanks!
