perhaps you missed the issues a year or so ago when the Intel drivers happened to break for some (but not all) Intel cards, just in time to get into a LTS release.
It was not a fun upgrade for a lot of people, especially ones who thought they had good hardware because they weren't running a AMD or Nvidia video card.

Exactly - a fixed release timeline is really a bad idea for anything that depends on hardware (including desktop environments using 3D, these days), though a flexible release date would only help if significant bugs are taken seriously.
Ubuntu often works well on lots of hardware, but getting specific hardware to work can be really painful, as with other distros.
