Apple computers rocks hard. I have an iBook and can say that it is extremely robust, stable, and without any doubts MacOSX is the most user-friendly operating system I have ever used.
I have a powerbook and I greatly agree. OS X is by far the main reason to buy a mac. If anyone truly wants reasons to support buying a mac I suggest you google it. I don't enter into these discussions as the majority of times people are closed minded to begin with - shown to be true here by a few instances of posts "littered with adjectives like horrendous, horrific, preposterous, and weedy" as said above.
Everyone should use what they're comfortable with, but at the same time people should not pass judgement on others when they are completely uninformed.
