Apple is throwing a bomb to its enterprise server users (only if there aren’t many) that Xserve server will be available until January 31, 2011. Full support continues even after Xserve is not available for purchase. Apple has published an Xserve Transition Guide that advise its user to consider Mac Pro or Mac Mini with Snow Leopard Server after that date.
This is a major move by Apple signaling its focus on being a consumer company, i.e. Apple wants to be less like HP and more like Sony. It is interesting to see if there will be a server edition of Mac OS X Lion coming out next spring.
