800gb is plenty but remember, you need to devide the hd so that both Mac and Microsoft can reside on it.

Bootcamp is provided by apple and will be built into Leopard. The other two programs are 3rd party programs. Bootcamp provides a way to have two operating systems or more reside on the same computer and makes them selectable at boot. The other two provide capabilities allowing both or all three etc to run at the same time. The Virtual software packages as they are called do have some issues which for your purposes may or may ot outweigh their advantages. Bootcamp has some disadvantages overcome by the virtual applications but has disadvantages as well.

The virtual packages devide the ram on your computer into chunks in order to run each os and its respective apps. Bootcamp dedicates the entire ram set to which ever os is running at the time. The virtual packages may not run all applications properly especially some assistive technologies and have access issues as well. I have not used them so cannot be specific about this but there are those who can fill you in.

When using bootcamp, you need to decide whether to use fat32 or ntfs for your windows partition. fat32 limits you to 32gb for that partition and ntfs allows as much space as you want but you cannot write to the ntfs partition from the Mac OS. I have not been able to get sound recorder to work on my Mac using bootcamp running windows.

I hope that helps and that others will chime in.

Could someone tell me what the differences are between fussion, parallels i think it's called, and bootcamp? If one were to run Windows in conjunction with Mac, how many gigs of space does xp take up? If you only have a Mac Mini with an 80 gig hard drive you don't want to junk it up with a big ol' windows install, that is why one would switch, to get away from Windows right?
