BlackBerry - access your email from anywhere

I want a blackberry!!!
Ever since a friend of mine who visited Israel a few month back showed me his blackberry device, I decided I had to have one. Can you imagine reading your email wherever you are?
it's a cool device that keeps you always connected to your email (which, let's admit it, has become a work tool that we cannot live without). I liked the mini keyboard in the device that allows for pretty fast email writing. Now I need to figure out which model I want.

Let me know which model you recommend...
