Apple in all their wisdom sent me a free upgrade to Lion if I purchased a qualifying product after a certain date.
I had so i did.
Buuuzzz!!! Wrong answer.
After the Lion upgrade (which I hate) from Snow Leopard (which I loved), my bootcamp partition is trashed. My VMWare doesn’t work and I am faced with a big recovery job. Fools rush in where angels fear to tread.
Hold off upgrading unless you don’t actually do anything with your Mac.
Update: Please see this for the solution.
