I haven't been this excited since VMware server was announced as being free.
Here's the rundown:
• Record/replay - which allows you to record entire the runtime state of the VM as it changes, and then play it back for debugging purposes
• Support for Vista as host and guest, and for Solaris 10 as a guest
• Virtual battery for laptops that shows battery life
• Easy virtual disk mounting for Windows so you can mount a VM disk file as a drive
• New virtual hardware to include USB2 and a 64-bit sound driver
• Max RAM moves from 4GB to 8GB
• Improved and more flexible shared folders
• Cross-platform drag and drop and copy/paste operations
• Improved inter-operability with remote control software such as VNC
• Support for multiple displays
• Experimental support for quad-core machines and more virtual PCI slots
I just can't wait!
