I have come to like Ubuntu 13.04 quite a bit. Raring Ringtail marks the first Ubuntu installation lasting more than a day in one of my machines. It´s been a two year hiatus and now that I am getting to love it again, I can´t help but being a bit concerned with everything I am reading about Canonical changing the core of Ubuntu.
News has it that Ubuntu will, over the next year, change its software packaging system to what they call "Click Packages", abandon X and forget about Wayland to embrace Mir and, last but not least, transition Unity entirely to Qt. The idea behind this sequence of changes it to provide a unified foundation for all the Ubuntu platforms (mobile + desktop, maybe TV?) to build upon. Given how quickly they want it to be ready, though, and the fundamental nature of all the changes, it is quite the ambitious plan, to say the least.
