I guess this is significant - but.... what I really need is the other way around - I want to run linux but run windoze applications inside of it.
I know VMware is sposed to provide this and I'm sure it does - but doesn't one have to come up with a copy of windoze to run inside the VMware environment - or am I missing something here?
There are other VM options as well--Xen is probably the best-known non-VMware. I'm not sure how well it works yet, but I don't believe that Windows is suported.
WINE is another option. It comes in assorted flavors--WINE, Cedega, and CrossOver Office. Choose the one that best fits your needs.
You didn't mention which Windows apps you want to run under Linux. I've run Office apps, and a few games directly under Linux using Cedega, but not all apps/games are supported.
Best thing I've ever found for running Windows apps inside Linux is Crossover Office 5.0 Pro. I use it to install iTunes (right now iTunes 4.9 is the latest release to be officially declared compatible).
