This a i3 M370, but I run a 32 bits OS because I got tired of running 64 bits with applications with no support for 64 bits (read: Flash browser plugin and Skype).
After some time I've found that there's no real advantage for me on a 64 bits OS for a laptop (ie. I have only 3GB of RAM, performance looks the same, etc).
