The difference between Mac and PC can best be summed up by what happens when you try to print something.
When I print something on my iMac, which is rare because I like to be as close to paperless as possible, printed sheets come out of the printer.
I'll say it again. When I tell my iMac to print a document, magically the requested documents appear on my printer. No fanfare, no fuss, it just does exactly what it's told.
At my day job, I'm forced to use an ancient Windows XP box. I need to print quite a bit more at work than I do at home, but this is unavoidable. So, what happens when I tell Windows XP that I want to print something?
OOOH OOOH Look at me! I'm printing! I'm doing what you said! OOOOH LOOKIE LOOKIE LOOK AT ME!!!! Did you see what I did? I PRINTED!! OOOH!
Windows XP feels the need to announce to the world, via a large pop-up dialogue box, that it did exactly what I told it to do.
Why in the world would I need this box? The pages coming out of the printer should tell me that the request worked. I don't need an additional, extremely annoying popup to tell me what I already know.
