So often wrong
One of the things I remember fondly about Guy is how wrong he could be.
A recent article (well 2008) at http://www.pcw.co.uk/personal-computer-world/comment/2224643/kewney-large-head-cloud is a good example. He clearly couldn't know about Dropbox and other cloud-based products that would bring it withing everyone's reach.
Nevertheless, I know for a fact that his world-view often promped developers into proving him wrong. So in that sense, maybe his being right actually made him wrong, with hindsight.
Guy was a great journalist and a good friend.
