        Actually (and I can't remember the source--think it was an IBM guy
who worked on the 701's that John referred me to), the 701 screen
supposedly does 256K colors in the 16.7M color mode.

        As for me, I just run it in 32K colors generally--looks quite
beautiful to me, but then I save the desktop publishing for a separate
desktop machine (where I run in 16.7M colors & higher resolutions).

        Oddly enough, the 701 Manual (or some associated document) suggests
that running in 32K color mode as opposed to 256 color mode extends the
battery life slightly.  Strange, eh?
