Are Apple building a MacOS X-based PDA?
This site seems to think so, and even
has a photo of a mysterious titanium-coloured object bearing an Apple logo.
I'm not sure how suitable MacOS X (being a rather large Mach UNIX) would be
for the job; though I hope it's better designed than the Linux-based Agenda
PDA. (I got one (for free, granted) some time ago, and it has been gathering
dust, partly because it doesn't do the job better than my aging Pilot, and
partly because it drains batteries at an alarming rate, even when off.)
