Stuart's got my main motivation, I'll add a few numbers to back that
up though. Looking at the OpenMoko binary images for use on the
Neo1973 as an example, it's clear that adding a minimalist X server
adds at least 5MB to your dependency footprint... and that's without
font or authentication. Each additional 'driver' such as FBDev, SVGA,
etc, seem to add 0.5-1MB extra to it.
>From existing proofs of concept I've worked on, I believe we can
address the usecases I mentioned in well under 1MB (I'm being
conservative here, I think under 400KB would be possible). It goes
without saying that the above footprint sizes exclude the JRE ;-).
For single-use devices or kiosk-type software, the extra size of an
XServer just isn't necessary and could be used for more image/sound
