Ubuntu, Kubuntu, Xubuntu "Mir, Ubuntu's in-progress replacement for the X Window System, is being used internally at Ubuntu developer Canonical and will be available to all users in the next version of the operating system. Mir was announced in March, with Canonical saying that a new display server is needed to power the Unity interface across desktops, phones, and tablets." Anyone here experience with Mir? Is it any good? any downsides?

Slower applications when emulating X

XMir works fine for emulating X applications, but there is a noticeable performance hit. I don't think this will be an issue for applications that use qt or gtk, as they will be abstracted out and can then run on Mir just fine. But applications that don't use this layering and are written closely to X will definitely run slower. Unfortunately, these tend to be the more demanding programs (like games). It's going to be a rough transition.
