Okay, Here's my 2 cents' worth ....

Another school of thinking says that human eye can differentiate
thousands of colors but cannot appreciate it very well. Confused ?
Basically, its like if you show a human a 1024 color screen and
then show him a 24-bit (16 million) color screen; he will not be able
to tell the difference. BUT, if you put the two screens side by side,
he can tell the difference !

I pretty much believe that 256 colors is just about enough. Of course
the more the merrier, may be 1024 ??

But I really believe that we need at least 16 bit (or 65536 colors)
colors to really do nice display. Why ? Well, these days, we really
want multiple Windows on screen each having their own 1024 palette or
so. So, I think PC's 256 color standard is deficient. Mac's 24 bit colors
is overkill but I don't mind if the display card is not too bloody
expensive.
