- The PowerBook 170 has a monochrome active matrix screen giving fantastic
- CRT-quality viewing angle, contrast and refresh rate. Great for several
- people looking at the screen simultaneously.
-
- The PowerBook 180 has a similar active matrix screen but with 16 shades
- of grey. The vertical viewing angle suffers somewhat compared to the
- 170, but the horizontal viewing angle is as good. I'm not joking when I
- say it's still clear and sharp approaching 180 degrees.
-
- The speed of the 180 Active Matrix acreen is good enough to display
- QuickTime movies in grey scale.
-
- Apple will be releasing a colour PowerBook, the 165c, on Feb 10th costing
- less than the 180 because it'll use a passive matrix colour screen. (In
- effect it seems that passive matrix colour is cheaper than active matrix
- grey scale!)
- Sometime around July they're apparently releasing an active matrix colour
- PowerBook costing considerably more.
