Amazon’s Jeff Bezos is doing great stuff – by making utility computing, SaaS and utility retailing a reality – simple and inexpensive. Personally, I think this a great vision (not Jeff’s exclusively) and great execution (Jeff’s exclusively). For example, (a subset) Amazon S3 is already touted as big success; and EC2 is just being unveiled. I think the potential of this easily dwarfs the success of Amazon as an e-retailer (A thumbs up from KPCB too!).
