Even at one bit deep the faces are recognisable, with colour
they should be even more so.
Screen resolution is not increasing. 100dpi screens have been
around for many years and I've yet to see substantially higher
resolution. Colour screens in particular have technological
problems going further. The reason there is no big push is
that no one can see the pixels at higher res anyway. Half inch
images are a good size.
Screen real estate is valuable and people would rather not use
more than necessary.
Variable size icons are a pain to tile. Compatibility with
existing versions of the faces software becomes an issue here.
Higher res means more bandwidth.
