This is to keep OS X off of other companies PC hardware, right?

I'm just guessing but it sounds like they thought they'd be able to keep it locked onto Apple hardware using other methods but when those failed they gave up and locked the whole thing down.

Hopefully they'll work it out in such a way that it doesn't limit legitimate users.

This seems like a stupid arguement given that the #1 most popular commercial OS has a closed kernel. And then when you consider how horrible the acceptance of Linux on the desktop has been along with the fact that Apple clearly wants to remain a consumer-oriented product company, it becomes even stupider. Like they want to support people running a bunch of hacked up kernels with poorly written "enhancements".

Biff, based on what I read in the fulll column, these are the people this will most affect:

http://www.apple.com/science/

Based on that link, wouldn't you say that Apple is interested in that market? It looks that way to me, anyway.

The OS X kernel has never been open. This is non-news, and misleading.

OK, you silly little anonymous person, why is xnu (OS X's kernel)here? It isn't in the x86 directory.

You are non-accurate, and misleading.

I think the lock down will only effect Developers. Most likely, if you are a legitimate developer, Apple would provide the source code. Also, at a marketing standpoint, charging for the source code can create another revenue source for Apple.

Apple is in Business to make money and increase share price. Couple of things that effect share price is revenue growth, actual and potential, and market share. If company fails to grow its revenue or increase market share, ie Cisco or MicroSoft, stock price will be stagnant or decline.

...and I think the "virus" explaination is crap too. I think it can be shown that while an open kernal allows a virus writer to take advantage, the open source community can take away that advantage much faster than a monolithic company can. (How many windows patches came too late for you?)

I think Apple is doing what it can to control it's operating system and keep it off non-Apple machines.

I understand it from a business perspective but I don't like the "virus" white-wash.

My bad, I posted without digesting. Apple is saying it's about piracy. Just what I said So I applaud them for being up front about their motives.

But I do think it can be a double-edged sword.
