I run a MAC, i love it. BUT the best PCB design tools and routers seems to be Windows based, as do a few 9 growing smaller) number of other applications...PBP3 :-)
So for those Windows based applications that i cannot live without, i run Parallels Desktop and with the Windows applications in coherence mode, they sit on my Dock just like any other Mac app, I run Windows apps on my Mac and have the best of both worlds.
