Here’s one answer: Who cares? Let’s face it: “desktop” is a concept created by marketing departments, to characterize a platform that has had all its serverlike tendencies carefully neutered to avoid cannibalizing sales of more-expensive products from the same company. Back in the 1990s, we had “Unix workstations”, which combined both “server” and “desktop” functionality into the one product. Windows NT couldn’t compete with that. But Microsoft’s marketing managed to convince management at Unix-using companies that they didn’t need “server” functionality on the “desktop”. And so, the mediocre product was able to push out the more full-featured one. But Linux is still a workstation platform. In fact, it is king of workstation platforms, and has been since the death of Unix. If a “desktop” platform is all you want, then by all means stick with the cut-down products from Microsoft and Apple. But if you want something more, come to Linux.
