I am a system admin at a 600+ employees company with all windows and some linux (VMWare ESX 3.x). I am in charge of all our SQL servers (6 MS SQL 2005) and Backup servers running Windows. I converted to Apple last August when I purchased my 24" iMac. I find no need what so ever to run bootcamp or fusion or any other virtualization software on my mac. I even went as far as configuring bootcamp on my iMac just to erase it after 2 hours. OS X either has everything built in or there are windows equivalent programs that are IMO better then their windows counterparts. Remember now I am speaking from a home computing perspective not hardcore gaming/business point of view. For home computing I think the virtualization software is a waste of resources. OS X is such a powerful OS and there are hundreds of thousands of programs out there that will pretty much satisfy your every need.
