What exactly do you not like about Unity7?
The recent announcement from Canonical about doing away with Unity and Mir stirred up quite a storm in the Linux world; expected, given that Ubuntu is probably the most popular Linux distribution.
Mark Shuttleworth has since then also made comments like these, which signal towards a deeper issue:
"The whole Mir hate-fest boggled my mind - it's free software that does something invisible really well. It became a political topic as irrational as climate change or gun control, where being on one side or the other was a sign of tribal allegiance."
That's really Unity's core failure; it was ambitiously designed to adapt to multiple formats (phone, tablet, laptop, desktop) and in the end, the required compromises led to a UX that wasn't _great_ in any form factor.
Microsoft tried the same thing with Windows 8 and had the EXACT same result. They alienated their core market of desktop/laptop users and completely failed to find traction in mobile/touch. Much like Ubuntu, Microsoft backed off that strategy with Windows 10 offering more substantially tailored experiences for mobile and desktop use.
Apple was smart and never tried a one size fits all strategy. Their mobile and desktop UX is entirely different.
Circling back to Unity, I also hate the window controls on the left. Not that controls on the right are intrinsically superior, just that I'm more accustomed to that location from other desktops. It seems contrarian and I just can't get used to it.
