Apple won't be switching to Windows. I can't quite figure out where Dvorak was coming from on that article. I read the same one, and also read some other articles talking about this.
My two cents...
Boot camp was an incredibly smart move for Apple. "Well let you run your OS on our system, but you can't run ours on yours". For one, they are sticking it to MS. It really shows off the abilities of Mac systems, as well as their willingness to accomodate other systems. It's great incentive too. Why buy a system that can only use windows (excluding *nix here), when you could buy a Mac and have OS X, BSD (backend), AND windows available to you. The pricetag may be a bit higher, but it's well worth the money if you need/want OS X only apps, as well as windows only apps.
Games. This is a big one. Since so many game devs are slow to moving into cross platform compatibility, this allows a solution to the "But you can't play games on a Mac!" issue. Now you can.
On top of this, there has been talk about built in Virtualization in 10.5. Weather this is a realtiy at Apple, I don't know. I think that what they would shoot for, would be a solution where windows can run as a sort of background service, and you can simply launch windows programs that you want. Sort of like classic supprt, but much much faster. You'd be running Windows natively, so you'd have full speed and graphics support, since it's all standard hardware.
As far as the firewire goes...am I mistaken, or is USB 2.0 much faster? I want to say that it is.
And switching...tons of people switched. I know a whole lot of people, mostly through work, and mostly computer guys. A great deal of them either switched, or added a Mac workstation to their home network. Others are planning to switch now that the MacBook is out.
I feel that right now, Apple is making all the right moves, and with Microsoft's "upcoming"* blunder**, now is the time to strike
But hey, that's just me!
*Vista will never actually be released. (That Duke Nukem game - you know the one I mean - will be released before Vista)
**Even if it does get released, we already know it's going to be ME all over again.
