Apple will remove the XServe server platform form the Apple Store on January 31, 2011, suggesting instead the server-oriented Mac Mini with no optical drive or the Mac Pro. The platform, introduced in 2002, allowed Apple a toehold in the heavy-duty IT world but the 1U servers have proven to be slightly less energy efficient than a standard Mac Mini and, obviously, much larger.
AppleCare and repair will still be available on the older machines and they will sell them until they run out of stock in 2011.
