Yeah!
The seamless mode is really awesome. But I guess, it would have been more seamless if we could just launch the guest applications individually, without having to bother about the OS which is running it.
Like the MS guys has implemented in the XP Mode for Windows 7. I suppose this is the enhancement of the seamless mode concept though, its pretty more awesome experience.
Hope that V-Box to launch this as Ultra Seamless Mode soon!!
Cheers!
