I've had this Razr v3m for about 3 weeks. Have a week left before I can exchange it. The razr is a nice phone but that large screen on the a900m is tempting (for web email, google maps, etc) I don't know if anyone has had both and could comment. I do like the razr looks and it seem to make nice clear calls. I'm not sure if it would be stupid to switch. I don't really have any problems with my phone.
This article does a bit of comparing between the two and a lot of info on the samsung... Hope it helps.......
:redface: Ok, that was just a test,,, and you passed....... Honestly I think sometimes I type faster than my brain thinks here is the link to that article: http://www.mobiletechreview.com/phones/Samsung-A900M.htm
The Samsung is a very nice phone but I'd go with the Motorola, simply because that is my preference. You can't go wrong with either model, IMHO.
