Joe my point was that not many serious Windows exploits or viruses come out when you take IE and Outlook/OE out of the equation. When something serious comes out then I know about it and patch all boxes, but that's much less often w/o MS browser and e-mail running on those PCs.
For my own notebook I use Outlook 2003 and IE6 (w/ myie2 on top) and prefer it. But I use that PC every day and keep it updated as a matter of course.
I block kazaa and a few other things with the hosts file too on those PCs and have no problem using them on my own systems
I can't imagine switching an office over to Linux. I get enough dumbass windows questions as is; I can't imagine totally changing someone's work environment and teaching them all how to do tasks over again.
