I think you are correct here. I seem to recall mention of some
of those earlier devices at the time of the Microsoft announcement. I
seem to also recall some of the reliability problem they had. I believe
they were extremely fussy about the surface they were on.

I would agree there. They did something to improve the reliability
on a wider variety of surface textures, though. Is that innovation or
merely getting a good idea, that's been around, to finally work? Don't
know. I didn't find the idea itself particularly innovative. The fact
that they did get it to work reliable is something to be said.
The marketing is a given, of course. Particularly in the face
of the preception in some camps that this style of optical mouse was
unreliable.

Agreed.
