I think that Microsoft is finally running a bit scared because of open source. There's no other reason for them to be playing tv commercials for the new Office. I bet they start to reduce the prices soon, too. Not just their software, I think that they're going to have to reduce the cost of their training programs, too. Might not happen too significantly presently, but in the next 5 years, they're going to have to jump through hoops for us, not the other way around.
On second thought, maybe it's just wishful thinking.
This is good stuff. Thanks for the tutorial.
