forgive the question, I'm confused. what is the difference if u use a virtualizer vs. Boot Camp alone? What do they do or allow u to do that BC doesn't? then what is the point of BC?
I could use Boot Camp alone, but it would be slower.
My business is developing cross platform 3D plug-ins. I prefer to do most of my coding in Visual Studio in a virtual machine so I can immediately compile the same code in XCode and test both platforms at the same time. I also don't have to reboot to test a customer issue that comes in from either a Windows or Mac user.
On a personal level, I use iCal for my schedule, but MS Money for financial stuff. With virtualization, it all runs at the same time, no problems.
Basically I can use my favorite tools when I want to without reboots.
I still keep a bootcamp partition running because occasionally I play something that's not available on the Mac and there are a few things I use that just flat out run faster on Windows. When render time is an issue, I'll go to bootcamp and render there. This however is less and less as time goes on. Mostly these days I try to avoid it because of how flaky the Apple wireless keyboard and mouse behave under Vista.
