Vpn... I am able to use a Nortel VPN connection on the Mac side and use it in Windows in Fusion. That alone is a killer element for me. One connection, both sides using the tunnel without any screwing around. I've had a couple odd freezes with shared folders, and performance isn't up to Parallels, but this is going to give me an option, and I hope the Parallels guys can step up here. Haven't tried anything 3D yet, but will just for kicks. I think networking is very important, and ease-of-use more so.
