It's simply the best, better than all the rest: VMware Workstation 6.0 beta can be downloaded here. Besides support for Windows Vista and multiple monitor display, VMware Workstation now integrates with Visual Studio!
Workstation integrates with Visual Studio and Eclipse so you can deploy, run, and debug programs in a VM directly from your preferred IDE.
How cool is that! Currently I'm enjoying some time off from work, so plenty of time to poke around with some new stuff ;-).
And to conclude this post:
Have a nice Christmas and a happy New Year. Peace!
