One operating system to rule them all
One operating system for all your devices... one operating system to rule them all. This sounds like a bad spin off for the Lord of the Rings trilogy. Sure, I think most people would agree that having a consistent look and method for accessing device features is a good thing. But, is having the same operating system the best way to accomplish this? It cracks me up how this idea seems to be the lead in for most of the articles I read about Windows 8 and 10.
I think most of us have several different devices (desktops, laptops, tablets, cell phones, etc) and have different reasons for owning each of them. As much as I love my cell phone, it would not be my first choice of device to use to update a spreadsheet, type a 2 or more page report, edit a family portrait, or any other project that would better suited for a large screen, keyboard, and mouse.
Rather than coming up with one platform for all devices, I think Microsoft should cater to the strengths of each and then focus on an interface that will help emphasize them. I think Apple caught on this vision early on and recognized that people have different reasons for using their phone and desktops. Accessing programs, personal files, and settings is similar, yet they have two different operating systems.
