I think that should be 88 bytes/line/bitplane?  At four bitplanes, 2048
bytes takes 6 display lines.  So the screen-real-estate problem isn't
really that bad.  The big problems lie in bootstrapping a critical mass of
users and developers for this device.  (Though I'll probably go for it just
to hack around with, even if no commercial software ever uses it.)
