I'm a little disappointed that the interview didn't mention COLA/STEPS as I think this is by far the most interesting thing Kay has worked on of recent. Obviously he's been an innovator throughout the history of computing and it makes sense to interview him abotu the overall direction of the industry, but it'd be great to hear about COLA especially as there's very little written about it aimed at a non-academic audience.

http://www.vpri.org/vp_wiki/index.php/Main_Page is the primary resource about COLA at the moment, if you're curious.
