Macintosh VS Windows

I'm now using Matt's Mac laptop.
I've been using PC (Windows) all my computer literate life (25years?).....

And I am wondering, why didn't I use Mac earlier? And why do people still use Windows?
Nicer display is one, but a better stability and speed is another.
APPLE users may ridicule me, but it's never too late to convince others who are still using PC.

Just an update of my latest discovery.
