Sorry, I'll have to disagree on the Unix statement. I started on PCs/DOS back in the early eighties (Commodores and Sinclair zx 80s) moved to Vax, moved back to PCs and DOS, found Macs and finally came back to Unix. My own preferences are Unix for development - Solaris, Debian, Suse and Red Hat in that order. I just find earlier Mac OSs and Windows cludgey, probably due to my own lack of skills on these OSs.

My home systems - Windows 98, Windows 95, Windows 2000 on various old lap tops. I keep three sets of drives for Solaris, Suse and Red Hat, popping them in and out as I need to.

At work, its mainly Solaris, Tru Unix 64, SGI, various Linuxes and Windows 2000/Max OS X. I like to use Hummingbird as the windows emulator for Unix, MacX for Macintosh.

Tools - I use the various Unix tool ports to Windows mentioned earlier. I do find Visual Studio useful for cobbling together C/C++ projects or trying to port code to Windows.
