It's all about timing. Cooper did a fair amount of ethnographic work,
and our personae guided the design work, particularly the interaction
and visual design. As far as hardware design (touchscreens, inputs,
outputs, etc.)... well, the train had already left the station.
We've all been there, right
I just posted some of my thoughts about the Litl, after seeing it at
last week's IxDA Boston meeting.

Long story short: I think we were all surprised to hear what sounded
like their utter disregard for (or ignorance of) the user research
process.
