I have 20 years in IT, and made the switch to Mac a little over a year ago. They're reliable, easy to use, and have almost everything you need out of the box. I run VM Fusion for the times I need Windows, or Linux. But usually I can RDP or VNC to remote systems as needed.
Oh, and I support 30 plus servers/Windows AD/Exchange/SQL, remote sites via MPLS, Cisco Switches, Routers, and Firewalls, and an IP PBX for 500 + users from my Refurbed, white MB C2D. I only mention that, because some IT professionals will say it's no good in a Windows ENV, etc., and that's total BS...
Go for it, and good luck!
