Slow? compared to what? The WM 5.0 devices I have used kick the crap out of any palm device I have used. I mean, the old 2003 devices were a bit on the slow side, but that OS was crap. Yeah, blackberry is pretty good from the user's prospective, but for sysadmin's it's a NIGHTMARE. Lock down your network, but some dick in a higher level wants you to set up a blackberry server, oops big hole in your security, because of how easy it is for your blackberry to get a virus. And what does RIM say about it? "If you set it up right it isn't a problem", yeah, if you set it up "right" it's totally useless. If the blackberry market wasn't so big, Cingular would have dropped support for them, and as is, at the corporate level there is a big push to get people to switch to WM for security reasons.
