Ubuntu's multi-touch framework allows for occasional touch gestures, and
provides one of the ingredients for a touch OS. But Ubuntu is not a
touch OS.

If anyone did make a good touch OS based on Ubuntu, it would
not have a small panel at the edge of the screen (or at least, not one
with multiple target areas), for the reasons you give.

Netbooks are not touch devices either. Some netbooks may have touch
screens, but expecting people to use a vertical touch screen for any
substantial period would be disregarding how human arms work.

Any sensible touch-based OS would not have Close buttons, Minimize
buttons, or Maximize buttons. That has nothing to do with where the menu
bar is in a pointer-based OS.

We're using a unified menu bar in Ubuntu not "to persuade the users from
the Mac with the similar interface", but because we think it's the best
way of presenting menus in a pointer-based interface.

A pointer-based interface takes advantage of screen-edge targets (like
the menu bar), compact controls (like menus), and tooltips (as in the
Unity launcher).

A touch-based interface takes advantage of flicking (like for
scrolling), and complex drags (like twisting to rotate an object).

They are very different things, and a design that works well for one
will hardly ever work well for the other.
