During 2008, I have gotten 4 pilots and 1 Mechanic from my hangar to switch to Mac, all bought 2.4 MacBook's, AND EVERYTIME I RUN INTO ONE OF THEM IN THE HANGAR, THEY KEEP THANKING ME AN TELLING ME HOW WONDERFUL MAC IS!!!!
These guys used Windows machines, and would only marginally use their machines, now they are using digital cameras with iPhoto, making slideshows, they sync their ipods, they download and edit video, they sync their phones with bluetooth, it's pretty amazing how as soon as they try a Mac they become addicted.
For those Windows only apps, I partitioned my drive and installed windows and the windows apps like Microsoft Flight Simulator or RealFlight G4 acually run better on the Mac than on the Windows machine.
I have used Mac's since the Classic.
