I find myself dismayed by this continuing argument. I grew up with computers (my parents got an Apple ][+ when I was in grade school, and it quickly became my obsession), and I love OS X. I dig SSF PCs, and love my Minis. But I would also love to see OS X on a broad range of devices; instead, Apple lately seems to be focussing their efforts on a few targeted subsets of the desktop market. That's great for when I need a device for a purpose that fits within Apple's specifications; it leaves me without the ability to use OS X when I need to do something else.
Both sides are right here. Apple makes superb desktop computing products. Yet, Apple continues to refuse to make a wide range of desktop products. Perhaps they're restricting themselves to the most profitable subsets of the market; regardless, it is a point upon which people can criticize this company.
