You might have missed it, but Apple got there first for once. Their last iOS added syncing app states between all their platforms iPhone, iPad, Macs etc.
App states – but not apps? The app vendor has to have made the app for each platform separately, no? The MS offering allows the vendor to create a single app and it will magically work on all Windows platforms. You only need to buy it once.
That I doubt, who is going to want to edit a 500k line application on a 5.1″ phone in fully featured version of Visual Studio?
You picked the most obvious one for effect, but chances are MS and the other vendors will think of apps and usages that you haven’t 🙂
And most 3rd party productivity tools are on all platforms
I don’t think you’re following me. Currently, you have to write your app two or three times for different platforms. With Windows you will only need to write one. Not the same thing.
