For everyone who is new to VMware Workstation 7 and as a refreshment course for all other VMware workstation users, VMware has released a Free online course you can follow.
I must say version 7 of VMware Workstation is a lot faster with starting up and booting virtual machines then version 6.5 was. One very nifty and cute thing I use is I can run ESX 4 in a virtual machine within workstation 7, makes it much easier to show it to customers and colleagues.
The Online Course will give an overview of VMware Workstation 7, helps you getting started and shows tips working with VMware 7. (Also useful for 6.5 users)
