On the contrary, OS X is the best thing to hit Apple. Apple has gained followers because of OS X.
Many people only have both classic and os x on their machine because of quark, but quark finally moved to os x.
For the home user it the new macs are very useful. They come with butt loads of software. Most of the iSoftware just does the basics, but it does enough to get people started. I've been playing with iMovies, it isn't that bad of a program. It's a simple movie editting software, but it works well enough for someone who hasn't done it before or just wants something simple for home movies it will work well.
Apple likes taking risks. Their transitions are never pretty. Same when they switched to the powerpc, it was a risk and the transition wasn't the best but it was the best thing the company did at the time.
Everyone that I know that uses a Mac thinks OS X is the best thing Apple has done.
GoldenBear, do your own research. Take a single processor G5 with no more than 4 gigs of memory (configure sometihng that you'd actual buy and PCs right now can't go above 4 gigs of memory) to a Dell with simular specs. You really can't compare the processrs that well, Macs will be faster at the same speed, either way just get top of the line single processer. Try and get the same quality video cards too. Try and get the same type of hard drives. I believe the minimum for Macs these days is a 160 gig ATA, not sure if it is serial.
Don't include a monitor, Apple's Cinema displays are expensive because they are VERY good, they hardly compare to anything else. But Dell, like most such companies, rape you the cost of a monitor. You can get a good monitor cheaper from other outlets.
