Some PC nav software has radar integration. You're right about zooming
and detail though -- vector graphics allow this, plus they load faster.

Another advantage to vector charts, which I had forgotten, is that
they rotate all the chart notations right side up when you are in
"Course Up" mode. Raster charts can't do that, and they are slower to
rotate after a course change. "Course Up" is much more intuitive in
many situations compared to "North Up", but it does take some getting
used to.
