Drivers are BY FAR the #1 cause of problems in the PC-land. There are about zillion companies making components and peripherals for PC's, and large number of them couldn't code their way out of a wet paper bag. So we get drivers that are basically crap.
You can't compare computers with mp3-players. Computers are computers, whereas mp3-players are appliances. iPod is tightly tied to the iPod-ecosystem, whereas MacBook etc. is just a computer. A good one, and stylish, but still a computer.
When you buy an iPod you get something that no other mp3-player offers: a thriving ecosystem. You have iPod-accessories. No other mp3-player has something like that. You have iTunes, which no other mp3-player has. And you get the design as well. What does Apple computer give you that you can't get with other computers? Good design and OS X. Take OS X out of the picture, and the sales-proposal becomes a lot less appealing. Like it or not, there ARE well-designed PC's out there, but they do not have OS X.
Wrong. USERS are by far the biggest problem in PC land.
When is the last time you ordered a Dell, and turned it on and had a driver issue? Come on. This is not the old days. Trust me, I lived through hand setting IRQ's and shuffling cards in slots just because they were "Finicky".
Things are NOTHING like that today. Order PC from dell, or any other manufacturer, turn it on, and its going to work, no "Driver" issues.
All that said, the driver "Issues" really only occur on OS install, and upgrading, which 90% of the population does not bother to do.
All I am pointing out, is opening up the software a bit will probably make little or no difference in hardware sales, and open up sales to the "Tuner" / Geek crowd. Who have friends. Who set up systems. Who have influence.
I think the main question here, is whether apple is a hardware company or a software company. I feel that they are more a software company than a hardware company. Apple hardware is nice, and works well. So is sony. So are other makers. BUT, what truly sets it apart is apple software.
I mean, lets be realistic, apple has pc parts inside a shinier well built box. Any one company could do that. But what they have NOONE else has is an excellent OS, and excellent productivity apps.
