I would also say that Scenix may provide them with some extra incentive to
do this, as they have the internal osc feature as well (also an 8 bit
divider down to 32kHz which is quite a good idea).

The Scenix datasheet mentions 8%. Not that it really matters. Either you
need time accuracy (resonator) or you don't (Ext/Int RC). I don't really
care if I debounce a button for 30ms or 50ms if I'm using it to turn on a
relay or light bulb.
As you point out, the real estate saving is significant. An HC49U crystal
is bigger than the 12C509 and if you go to a smaller footprint part, the
price jumps substantially.
They've wet our appetite. Now we want more !  :-)

It would be interesting to see some data on that. (Not from you obviously.
You'd have to shoot me)
I'd like to see a comparison between Xtal, external RC and internal osc.
Just as a guess, I wouldn't be suprised if the external RC was the worst.
Anyone have the right gear ?

Steve.
