parallels, bootcamp or VMware?

im using a trial for VMware and it's ok i guess. I am having issues with the display window size though. i will be playing with both linux and windows from time to time. as i understand bootcamp is only for Windows, correct?

No.. Bootcamp can host any OS. Only problem is the bootcamp menu will show it as Windows even if the partition is running linux.

interesting. thanks for that. i didnt know it could do linux.

parallels can run linux too as far as i remember

parallels is a virtualization software. Most virtualization softwares support linux, windows even BSD installations

whats the issue you are having with the window size, i recently installed VMware and windows on my MBP, and i havent had any issues at all and usually run it full screen

I have also never had problems with VMware...

I have even used it during a Keynote presentation with a primary and secondary display, and VMware was able to do both a primary and secondary display for windows at native resolution for both the projector and my built-in LCD.

I have never had a problem with window sizes with VMware.

anytime ive tried to install unbuntu on Parallels v3, it errors out.

Neither have I. I run XP Pro, Vista, and Ubuntu and I haven't had any issues. Parallels also works well, but I find VMware has better performance.

It sounds like you need to install VMware tools. While running VMware click on Virtual Machine>VMware Tools...

VMware tools makes a significant difference.

EDIT:
Ubuntu runs better on VMware than Parallels, in my opinion.
