I've used most everything over the years, but have been an Apple fan since 1980 (Apple IIe). My first Mac was a 512KE purchased in 1985 when I was an undergrad at USD. I currently do my day-to-day work either on a dual 1Gig desktop w/Cinema display or G4 Titanium powerbook. Life is too short for crappy computers. I also have a Dell Latitude that I use if I absolutely have to use windoze...which fortunately isn't very often.
