I have been using BlackBerries since the days of the 850/950's. They rock for wireless emailing. I now have a BlackBerry 7230, and love it. I just upgraded the OS to a recently released 4.0, which comes with a TCP/IP stack for those who don't have a BlackBerry Enterprise Server. It rocks - I can now IM, browse the network and use any app that requires TCP/IP. I'm going to install a terminal application - imagine SSHing into my Mac wirelessly. The only negative is the VERY Windows-centric attitude of RIM/BlackBerry. They're JUST starting to realize that there's a world outside of Windoze out there... Anyone else here use a BlackBerry?
