It’s because the Start button isn’t “trendy”. No, really.
As put by Microsoft’s Chaitanya Sareen, the company had witnessed a “trend” towards using the new taskbar as a way to simply launch applications rather than navigating to links within the Start menu — like users have been doing for 15 years since the operating system first introduced the Start button and menu. While that may seem like the final word on the matter, it is not. In fact, Sareen went on to say that, “We’re going to unlock a whole new set of scenarios,” when describing the new Metro Start Screen in Windows, but despite the new user interface’s features and design, Sareen let loose, stating that “you can’t beat the taskbar”.
The technology world and the rest of the planet will see just how this plays out, when Windows 8 comes out in October.
