How can you get windows 7?

No legit way unless you get it from MS and they only gave it out to a select few and some conference attendees - it's only in pre-beta.

why would you need Windows 7? it is better to way for the Final Product than to test a Beta that may cause you problems and a lot of headaches lol

Some people like to tinker with OSs as they are released - get your head in the game early.

Get the final product, its much more stable... most concepts are streamlined... the only people interested in new beta OSes are programmers.

Yeah, just like how the initial release of Vista is just off the charts with performance, compatibility and less bugs. Seriously...

Aww yeah... This is why I'm not a historian. =)

Wow, I didn't realize Vista was around that long before wanting to be replaced so quickly. But then again I don't care too much for sci fi.  

And I understand how Linux has a lot of distros, but in the business world, that's not how it works.

Linux works everywhere, in microwaves, TVs etc. but its not really getting into people's computers...
