Why Apple never offer freely open to all mac users beta of their softwares? I mean it does not need to be the professional version of their software, it could be iWork 09 or iLife 09.

The less information leaked outside of Apple, the better it is for them. They RARELY leak betas, I can only think of iPhone firmware and OS X.

I think they also want as less crap possible to be out. For example, on Windows sometimes, I end up having so many betas that it is unbelievable. My system crashes and everything. Apple wants only final versions.

They definatley don't realease betas of OS X due to people from the OSX86 scene installing them on their windows PC's.

You can get developer previews from the ADC program (I'm using Safari 4 DP right now) but that's about it I believe...

...they do.

There's no need. Unlike Windows, Apple don't run OS X on a billion different configurations.

So, because is free they really don't care to release this to everyone I think Apple is too greedy with their softwares.

Bingo. Apple has enough employees to thoroughly test on all possible configurations. Microsoft doesn't.

I couldn't have said it better myself.

Well most of the time Apple's way works but sometimes it comes back to bite them in the foot like the problems with MobileMe. Even though they have fixed most of the problems they should have offered a public beta which would have allowed them to fix any problems that popped up and not get the bad press they did when it was released.

If they beta software like iLife and iWork, it will make for a boring keynote.

MobileMe was rushed, this is a little different. I think the Quality Control team was in the iPhone department, testing the new firmware
