Don't get this.
As consumers drive the world on innovation, is the IT the one that gives Microsoft, and others, their constant cashflow with their subcription programs, that's what Apple would like too, that's why they have a server version of OSX, and are trying to get their systems work with Exchange and other software.
The importance of IT in the world is so much, that thanks to them we got Laser printers, inkjet printers (yes, the inkjet was designed for offices, as a replacement to the expensive laser printers) and flat panels, besides networking, and internet, if you think, more that 20 years ago, only companies had internet in their office.
Mass market products are almost tested in the office, not all of us had that amount of money when LCD panels where first released, or notebooks or CD writers, god! those where expensive!.
Apple is sitting on elitism and "self blindness", to the point as to change the core of their machines, it's processor to the Intel camp, in essence, a PC, a good looking one, but still a PC, with EFI, big deal, soon the PC will get one. I think that more that creating a new machine, Apple evolves to a new concept of machines (I know about this, as i used to have mac classic around when i was young, using appletalk, not ethernet, and even programming in it).
More than a replacement for PC's, the real need is an evolution, Windows Vista is going to the right place, it's not perfect, but better than XP in many things, just too bloated, but's that another story, anyway, we need another version and a real competition, something that may come true with ReactOS, as an alternative to Windows (i'm not including Linux, the idea is a Windows alternative).
It's true that people wants a system that just work, but it's also true that that same people, once they start learning, want to know more, want to do more with their PC, expand it, modify it to their own personal taste, and they must be allowed to do so.
What happens when only one manufacturer controls the market?, there is no possibility to customize your system, it turns out to be the Ford T of computers, Apple controls their own market too much, for stability purposes, and that's good, but i want flexibility also, and stabillity cannot be warrantied in that case.
So, it's easy to say, "Apple is good, PC's are bad", also calculators are good, but you don't want to install a new 3D card on that, you know it does what it does, nothing more, but PC can do more, much more, as Apple computers do, it's a matter of preference.
I choose PC, most of us do, and i'm happy, even if it hangs from time to time, that's the fun of living.
PD. sorry for my english, as isn't my native language.
