Looks like installing the Bootcamp Beta will void your warranty, check out this thread: http://discussions.apple.com/thread.jspa?threadID=432346&tstart=0
Think twice about install Bootcamp until it comes out of beta or you could be in a bit of a pickle.
Edit: There is a lot of confusion, it may or may not void your warranty, but as a beta Apple says you are on your own, if you install this you wont get any help from us.
With the addition of BootCamp to Leopard you can triple boot an Intel Mac with Linux, Windows and OSX with little loss of performance allowing you to play windows games at very reasonable framerates.
I'm gunna start saving now :P
If you have a new Intel Mac then today is your lucky day.
Apple will be including a partitioning and booting system which will let you run Windows XP alongside OSX.
Apple call it Boot camp and i know of a lot of people who will be very happy with this, Apple are even supplying all the drivers you need for Windows. Now you can have the best of both worlds, a high quality Mac Laptop which runs both OSX (for your creativity) and Windows XP (for DirectX gaming among other things), my guess is that when MS finally release Vista it will be installable too.
Here's apples page of info and where you can access the beta verison for Tiger.
FAQ with more detailed system Requirements here
This will defiantly open up the new Macs much larger market of people who are stuck with windows due to work or gaming requirements and in the future may even begin to blur the boundary's between the OSX and Windows.
This has certainly made the new Macbooks much more attractive to me, hopefully the new intel iBook wont disappoint and I'll snap one up in the autumn

There are also rumors of Apple release some APIs to allow Windows to run Unviersal Binaries, if they are true Apple are pushing in a very promising direction, the more news i hear about Leopard the more i like it. Only Rumors tho ;)
Edit 2: Bootcamp Likes Linux as well, for everyone who ever wanted to triple boot Windows Linux and OSX… get yourself an Intel Mac.
