More on Amazon: 1) Morningstar and CIRP estimate Amazon's Prime subs have surpassed 10M. They also estimate Prime members spend an average of $1,200/year on Amazon (twice as much as others), and that Amazon made $78 per Prime sub last year after various expenses. Bloomberg previously reported Amazon had only 3M-5M Prime subs as of Oct. '11. 2) Amazon Web Services is making a stronger push for enterprise accounts by adding virtual private clouds as a default option. Microsoft, VMware, and OpenStack supporters are pitching private and/or hybrid clouds as an alternative to AWS.
