Gladly. I'll give several.
Give me solid examples and I might believe you.
One guy who sits behind in my English class at school makes his own music (orchestral, I might add, he's brilliant). He always talks to me about how much he enjoys his MIDI keyboard. I've heard some of his work. Let me just say that he'd make a more than decent living as a conductor. The instrumentation is wonderful, and this is coming from a guy who's more of a pop-culture lover than high-culture.
For movies, that same person made a short dramatic version of the play "Walden" for the post WWII era section of our English book. He had to bring his iBook to show it to us. Though not professionally done, the sound and picture was crystal clear. None of the MPEGS I've seen afterwards can even compare to the quality of an iMovie.
I can't really give much support on art, as I don't know anyone who is an artist by trade, but what little I have seen has totally blown my mind.
IBM = International BUSINESS Machine. And it does mean something today. It's the term used for non-Macs; they'd probably be better known as PCs. Ever noticed how things either say "IBM Format" or "Macintosh Format" on some media (mainly Zip disks)? Well, there you go. IBMs were made for businesses to use (for accounting, databases, and such), so they don't have as good graphic capabilities as Macs.
And "IBM" is one plain, old term that means nothing today.
Obviously you haven't, and if you did, I don't call trying to use it for 5 seconds and then quitting as "fooling around". You might have tried the really old Macs, which I will even admit they needed some work, but the new Macs that I have seen have tremendous capabilities, and not just for multimedia anymore.
I've fooled around with Macs before...
...and I really don't know what's so good about a Mac for artists.
Buy a seperate 2-button one then, it's not that hard. That's what my mom did for her laptop. Even then, it would be superfluous. Macs are made for only one-button.
Just the single one-button mouse is enough to drive me nuts.
Judging from your comments, I would conclude that you are very biased about Macs. I understand preferences, but saying someone is wrong while not even considering they might be right just isn't logical. I also still think you haven't had enough exposure to them. Believe me, I used to think the same way you did, then I moved in with my mom, who still owns a Mac, and found out they're not as bad I as I used to think they were.
So do yourself a favor and don't criticize someone just because of what your preferences are.
