Thanks for the ping. After being on Ubuntu for a few months now, I see no reason to try to stay on the Windows Update Treadmill, and even less reason to buy Apple. Cost-Benefit analysis gets very obvious when the cost is almost $zero compared to the competition. Added to that is better virus protection than Windows plus Ease of Updating without having to buy a completely new OS.
Ubuntu rocks for me too
Unity drove me nuts :/
I am happy with Mint KDE ;^)
