Back in the 1990s we had X Windows in our computer lab and it was routine to run an app on one Sun workstation and interact with it on another.  This &quot;just worked&quot; with Linux and in 1995 I was laughing at RDP and crashy Windows 95 and NT.<p>Around that time KDE rocked the world with a beta release desktop that &quot;almost works&quot; but since then the Linux desktop has stagnated rather than advanced.
