Indeed, it’s a generalized problem. The reason why I pick on Ubuntu and Canonical is because they are the only ones that pushed the frontier of a GNU/Linux desktop. Since Canonical decided to spread its effort over to mobile I feel left behind. I wish them well and I wish that the development efforts of Unity8 and all the new apps will bring new life to the desktops too. I’m afraid it will take at least another couple of years before the new code will be up to speed with the existing code. That’s why I’m concerned: waiting two years to get apps that are up to the ones I have now… unfortunately I guess you’re right and there is little to do than to wait and see what happens.
PS I don’t use Wine or any other OS. If I wanted to, I could just buy the original stuff, OS X or Windows, and give up on my freedom-powered desktop.
