Pleased with virtual machines

I've got an Ubuntu virtual machine which I've used quite a lot recently. For one thing I can ssh onto other Linux machines (both real and virtual themselves), where my windows ssh client struggles with certificates.

I've got it mapping a windows drive via samba, and when I start it up when I need to use it it magically does the stuff behind the scenes so that I can access the files on the windows share without having to remap or anything. It's a bit slow for the first access, but considering the virtual machine has been suspended not shutdown, I'm still amazed at how It Just Works.
