Doesn't this only work for PPAs that are in Launchpad? And doesn't Launchpad have extra limitations that third-party repos don't?

Could this be set at boot time instead of install time? That way if RAM is added or removed (or if a DIMM goes bad) it will update automatically.

I'm sure Mir is a perfectly good replacement to crufty old x.org. But you know what? Upstart was a perfectly good replacement to crufty old sysvinit, and we all know how that one turned out. I predict this will turn out exactly the same; Ubuntu will go with Mir for a few years before eventually caving to community pressure and switching to Wayland, just like the ultimately gave up Upstart in favor of community-favored systemd.

Concerning DPI and trackpad integration, Ubuntu should strive to be as Mac-like as possible, at least imo. Macs absolutely win in the trackpad arena; multitouch works like a dream, configurable gestures aplenty to achieve whatever you want (of course, it could always be more customizable).

DPI scaling between monitors work exactly as you'd expect. Windows stay the same size when moving between high-DPI and regular monitors.

These two problems are two of the biggest reasons I don't use Ubuntu (or any Linux) desktop (I use a macbook with a headless Ubuntu Server box and, when necessary, X11 forwarding over ssh).
