I have a VZW 6900... The white housing is not near as nice the black rubbery ones from other carriers. The white housing is slick and feels very flimsy in your hand. The housing also has a problem with cracking in specific spots. It seems like it is a problem with quite a few 6900's. I was annoyed with taking mine back to the VZW store numerous times so I bought a black Sprint housing and swapped them out. Take a look at these posts from other sites for more info:

Other than the cracked housing issue the 6900 has been the best phone/pda I have owned!
It seems very fast compared to other PDAs/Phones I've used (XV6700, Treo 700w & wx, Moto Q and Q9M). The screen is very bright and sharp. I have included everything I need on the Today Screen so I do not use the Touchflo that much. It is kind of neat though.
If you can get around the possibility of the housing cracking (I understand if some people cannot) then I would highly recommend the phone.
