@dhanji - thanks for all your work on this - you've inspired us all. This post read a little bit like "This is more expensive to run in time and money than we thought - so we're shelving it for now." Can I ask - was this move triggered by (a) Google buying Sparrow? (and thus shelving other email acquisition plans) (b) Marissa Mayer moving to Yahoo (and killing a potential purchaser strategy) (c) The release of outlook.com (creating a high speed competitor with lots of resources for distribution and support and marketing).
