They are amazing -- so much better than the LCDs that replaced them. Try it outdoors with no backlight, for instance, or even under a desklamp.
You would also appreciate the PowerBooks 180, 180c, 270, 270c, 280 and 280c, which have similar technology in the screens (though with more greys/ colours). I like using them, though, in B&W as they are so incredibly sharp, and even better than a Compact's CRT.
