with Unix on the Mac. There are also options for virtualization of Windoze and Linux via the software Parallels although I have yet to test this out.
If you're trying to purchase a Mac so that you can run MS Office or other Windows only products without dual booting this is no longer necessary if you've got a Windows installation CD and a Linux system. I run Windows in Linux using Virtualbox (http://www.virtualbox.org) which is pretty much like a free version of VMWare Workstation. Do all of your research/graphics/modeling work on Linux and put it together using Adobe/MS publishing software in Windows running in VirtualBox. You can even share folders between the host Linux system and the guest Windows system without manually setting up a Samba server in Linux.
VirtualBox doesn't support Direct3D so most Windows games won't work. I haven't tried OpenGL apps, but what's the point when you can just run these in Linux.
