I do some web development work in company everyday, sometimes do Firefox extension development. So I need to switch OS frequently. I have used MacPorts and Fink before. They are great tools, but the software repository is not plentiful. So I use Leopard as my main OS, and run Arch Linux and Windows XP virtual machine on it now. Because I like apple’s UI, linux’s development environment. Windows? Just for playing games…
I often open multi tabs in iTerm, and ssh to virtual machine, use vim to editor everything. Certainly, servers run in virtual machine also. I just set my ssh login without authentication and port forward for others visit my server. And I use MacFUSE + sshfs to mount my linux’s file system.
