I am pumped that MS is becoming "Open to Open Source." This opens the door to the many, very powerful programmers that don't happen employed by Microsoft. (I do agree that Microsoft has a lot of money and have been able to hire very, very talented people, but I believe that there are also some very brilliant people who are otherwise occupied, and that their contributions, as labors of love, might well prove to bring out the nth degree in quality.) I wish that this was done years ago.
I also applaud Microsoft for their Express Tools. This will help to create a larger variation of talented programmers from a larger variety of disciplines, and will result in higher quality services that they can deliver, as well as many more and varied software choices for the consumer. Again, this would have been better if it happened sooner.
Like Tirak, Bill and Jojo, I too, wish I had a MacBook....sigh, maybe someday.
