Watching this TechCrunch video Hands on Windows 10 I was actually impressed with Windows. It made a compelling story as I sit here typing on my MacBook Air considering my hardware refresh which should include phones, tablets and laptops. But then the reviewer made a critical mistake. Granted it was not one that I would say cancels out my interest but it does sort of challenge his credibility.The statement was to the effect that Microsoft was unifying Windows across all 3 devices. Computers, phones and consoles; and that at Apple there was iOS and OS X, implying that they were not the same. That final comment about iOS and OS X is simply wrong. The core of the operating system for both is exactly the same code. This was never a secret and in fact was part of the propaganda used to sell iOS to potential developers. Now, of course, it’s all about the APIs and experience… and so the same delta exists in the Windows and Apple brands. While the point is taken to mean that the interface experience is different depending on the current user mode (Windows) some things actually stayed the same and appeared to be difficult to operate. Just how many times was he going to press the start button before it actuated?Windows 10 looked very interesting in the demo. Granted a lot of the code appeared to be W10-ish and so it was nicely visual. Even the fullscreen start menu. The colors were cool too. Unfortunately it’s the applications. At least in the windows ecosystem the themes seem to carry through the version changes (see Mavericks). W10 will not tell the complete story until it drops some of the backward compatibility.
