Sure did...

Your graphics board sounds quite good, even for twice the price, but
what H.Chu and I were talking about was some sort of graphip coprocessor
like the old 8-Bit ANTIC. ANTIC provided control over the vertical
arrangement of the screen (where to get the memory from and to display
in what resolution). I figured that a coprocessor that also tried to
control the horizontal arrangement (as great as that would be) would be
much to costly in terms of bus speed. Otherwise you'd need to
restrict the number of windows displayable pretty severely.

As to the guy, who responded saying that hardware cursors  were bullshit
in the nineties. We 'discussed' this offline and I just want to state
that 
     a) I am not convinced that hardware cursors are useless
     b) questioning my CS knowledge was maybe a bit hasty 

     
Anyway. I have seen a couple of adds now in various journals about note
book computers. I thought that the Atari notebook was doing handwriting
recognition, or am I wrong on that ? Most of the other notebooks don't
seem to be able to do that.
