I have been searching around. Looked at a lot of info about wayland pros/cons vs MIR.. etc.. I can only speak for myself in that I tried to work wayland back when it first came out. I forget which actual machine , but that tells me that this project has been sleeping just a little too long (at least from my perspective). It takes a lot of time and resource to surf-pull info about a development release (especially Linux based) and then have to wait. To me that equals downtime, number 1 on Computer science DON'Ts! Wayland (even currently) presents downtime and I am not one to suffer downtime gladly and I assure you that there are many other who don't either.
And that just does not go for wayland but also a lot of other developers pet projects which create enormous amounts of downtime. When I see downtime created I usually am very vocal about it.
If MIR presents the same swing and sway with Danny Kaye type scenario then I'll drop it like a hot potato, however , bottom line , we got to move on. Really , we are beating a dead horse here with wayland. I mean if Fedora continues to maintain and develop it then more power to them.
Personally I have been at this since 1963 (first as a TV repair technician apprentice in my fathers shop) and my eyes are really sensitive from sitting in front of and working with so many different types of monitors. Unity has brought relief to a long standing RSI of my eyes I have become intolerant of static screens with banal backgrounds. Unity is my sidekick .. and I more or less have to go where Unity goes. But that does not mean that wayland cannot be a success for others. And so more power to them!!
Anyone who develops software and puts it up for distribution should be well aware that it is going to get ripped apart from declaration of intergers to <EOF!! If developers are going to be sensitive about the various forms of critisism, the good, the bad and the ugly, then they should not be in development. Ubuntu (and most other software related) gets it mettle from U+1.
