David Wood on 30 years of PDA and smartphone OS...
(All About Windows Phone)

If you haven`t heard of David Wood before then you need to catch up a little. One of the creators of the Psion palmtops in the 1990s and then one of the architects of Symbian OS in the 2000s, he has tremendous insight - and, frankly, an impressive memory, dredging up codewords, anecdotes, and industry analysis from 20 years ago. I`ve covered his book here before, but the guys at the Nokia Chronicles podcast had him on this weekend and it`s a `must listen`.
