Open source 2007 and desktop Linux
It's going to be another year of desktop Linux talk. (Chart from Yahoo finance.)
IDC says this will be the year businesses revolt against Microsoft's anti-piracy efforts and back desktop Linux. Even ComputerWorld expects AMD to finally line up some proper graphic chip support.
Personally I think there are two desktop markets, the business and the personal. Desktop Linux adoption in business will be driven by the same forces driving it on the server, namely cost and the greater control it gives the re-seller.
