I love it. That's it - pure and simple. Been using it for a couple of days. The only things I had to handle was the following....
I use 1 24" monitor at home so I close the MacBook, let it go to sleep and then hit a key on the external keyboard/mouse and it wakes back up on the main display and I can keep the MacBook closed.
Other than that - I still like having a two/three button mouse. I makes sense. Having to move your hands to create a right-click is time consuming and I don't use a Mighty Mouse - I don't like the feel or design of that.
I'm also running VmWare Fusion for the Windows 7 installation and it's working like a charm.
