The OA actually seems to be claiming that it still sucks compared to Outlook. But this is similar in spirit to the endless refrain about how ill-suited the web is to application development and how far it is behind 20-year-old GUI SDKs. Meanwhile web application development continues to evolve and plow forward despite the misgivings of no small number of graybeards frantically waving their arms in protest. The bottom line is web is two steps backwards in terms of GUI, but four steps forward in terms of distribution, cross-platform, accessibility and availability. Gmail was probably the single most important bellwether of how Microsoft's lunch would eventually be eaten by cloud services.
