- Of course, I never said there weren't situations where Planar is more
- effective, it is just that I feel that these situations are becoming more and
- more less frequent. Today's computers rarely have situations where having
- planar is a real advantage (like what you describe below).

-
- Yes true. It all comes down to what a general purpose computer system would
- perform best with running today's applications and games in hi-resolution and
- hi-color modes. In that case I wouldn't go for Planar anymore as most of its
- advantages it had in the early days are of limited importance now.
