Dean,

I just noticed something interesting, looking at pictures of recent
Boeing and Airbus PFDs. For altitude, they are both pretty much the
same, but for the speed tape, Airbus does not have a big number at the
center of the tape but instead the number on top of the tape and just
a thin line at the center. After my experience today I like the Airbus
better because it is less conducive to reading the numbers rather than
"get the picture":

Take a look at the speed tape on the 777. The tape itself gives you
the course rate of change, while the window gives you the fine
resolution changes with the 1's place on the airspace as a sliding
digit. The Airbus doesn't give you that.
