You can tell this is a techie site. All this talk about operating systems, Kingston RAM and Intel architectures misses the point: Apple is a DESIGN company, NOT a technology company. The underlying technology is irrelevant!
Apple have never shied away from using their own interfaces and technologies where necessary. The iPhone hasn't been the most successful v1.0 (and now v2.0) phone design in history because of its technology. It's been successful because of how that technology was *exposed to the user*.
We're finally reaching the end of an era. The end of that first, learning-how-to-walk-and-talk stage of the IT industry, where technology finally learns about manners, wearing nice clothes and how to behave when dealing with its peers.
All the talk in this thread has focussed on PCs and how Apple uses the same hardware as everyone else. There are idiots here who have gone so far as to explicitly claim that this hardware is "identical"! And you call yourselves IT experts!? Since when have any two PCs ever been exactly the same, right down to the RAM chips and North Bridge? BULLSHIT! The IA PC is an open _hardware platform_. That means PCs have different graphics cards, sound cards, network chipsets, motherboard chipsets, RAM chips, even CPUs -- from Intel to VIA!
It's precisely because of the PC architecture's openness that end users have had to suffer decades of instability and poor, lowest-common-denominator software and interface design.
Yes, OS X now runs on a specific *subset* of PC hardware, but so was the original Xbox. I don't recall anyone _outside_ the tech-wanking fraternity caring a gnat's fart that Microsoft's box couldn't also run Microsoft Word! Closed, proprietary, systems are NOT a problem if -- and only if -- we have open standards for information exchange. We've been this route before with the likes of the Atari ST, Commodore Amiga, Acorn Archimedes -- all proprietary -- and not been the worse for it.
(CPUs aside, all consoles are now around 90% industry-standard hardware components and 10% "special sauce". All three current consoles use PowerPC-derived CPU cores.)
Technology is NOT the end. It is merely the means to an end. Enough already!
