umm - enter the nit-picker...
You can't compare Apple to Windows. Apple is a computer company, Windows is an operating system.
If you get straight what you want to compare, you can do so. For every type of software that runs on Windows, there is a comparable app that runs on Mac OS. It may be the same exact program, or a similar one written by another company. How each one works, whether the Mac OS app or the Windows exe completes the task better, is a matter of subjective analysis.
Or you could go the other way and compare Apple machines to - Toshibas, Dells, Compaqs or others.
I still have two LCIIs running System 7.5 and being used on a daily basis, and a couple dead pentium IIs stuffed under the bed.
Hands down the equipment rocks. (admittedly though - build quality has suffered a bit of late).
