Microsoft’s chief software architect, Ray Ozzie has said: “All the apps that count will be ported to every one of them,” he said. “It’s a completely different situation from the PC market, where software’s built to run on a Windows or a Mac” he said. “Mobile apps require very little development, so it’s much easier to bring them onto every platform”. What that implies is that developers will have to put less effort in to port their applications to other platforms, and "the apps that count" will get ported.
With projects like this for the Amplitude application, it certainly seems feasible, though I'm not sure I agree with "Mobile apps require very little development".
Does anyone out there agree?
