alright i just posted this in a different thread like 4 below yours heh.. but i'll paste it here for you too since nobody gave you a real answer..
i bought the v3c.. its alright, vzw took the entire GUI skinned it over motorolas to limit features and make it slower/retarded.. the UI is really horrible from VZW. The phone itself is alright at best.. there have been known issues with: keyboard being loose, mobile web eating your minutes when not using it, freezing up from time to time to the point that you have to remove the battery and reboot it. sometimes when i miss a call, check the missed call.. the missed call icon doesnt go away (which is really annoying b/c the icon adds an entire bar on the screen for this that removes the date from the external screen to show you that your phone is on vibrate, alarm is active, or you have missed a call.. something along these lines. (wtf??). the camera is pretty crappy also.. older phones have better camera options than the RAZR, also doesnt have an expandable memory slot like many other phones.. alright so there are some of the cons
for the pros: really clear call quality, size and design are awesome.. works as a phone, bluetooth is not crippled by VZW like all previous bluetooth phones (you can pair it w/ your computer out of the box w/o hacks).
i havent played with the sammy a900 but it does look nice and pack full of features like the razr.. dont know the quality though.
anyway.. all the cons aside, the v3c is a very nice phone that works great as a phone, its a keeper for me. I just wish vzw didnt mess it up so bad with their UI and other rediculousness that should not have been tampered with.
www.howardforums.com is a great place to get info on phones btw.
I'm a pretty good clutz, dropped the RAZR twice so far at 4ft+ in the air onto concrete.. sure it left a ding, but everything still works great.
edit: oh and one time i threw it (slipped out of my hand when i was swinging my arms for some reason.. wasted im sure).. and it flew about 10 ft horizontally and smashed onto the corner of a sub woofer on the back of the phone.. still works great :-D
