I read that post, and thought "should I rise to the bait?"
Sounds like daintdemure has sniffed the inside of a graphics tablet one too many times...
Time to chill a little, dude! Get out of the sun, eh?
It's just a tablet - no need to get your knickers in a twist - and for a 4-year old thread, too!
I think the original thread was simply pointing out some of the challenges of using some kinds of input hardware with OS X. OS X driver support sometimes may not be complete for those devices - and remains much the same today. Full feature support for all tablet functions? Not always there with OS X ... And Windows (maybe even some flavor of linux) can be an option that (sometimes) is worth checking (even for us Mac users)
Serendipity is a lucky guess !
