We have heard that the Windows 10 Start Menu is set for a redesign which will de-emphasize or even remove the Live Tiles, replacing them with static icons.
While some may imagine this means going back to the Windows 7 Start Menu, pundits believe something like the above concept is much more likely.
This would feature an absence of static icons, but a more dynamic canvas that is filled with your recent documents, applications and projects, presumably synched from whatever device you have been using over the course of the day using Microsoft’s cloud technologies.
The concept, by vGlad, would, of course, allow you to bring up a list of your installed apps, but I suspect this is not meant to be the primary workflow.
The biggest issue with the idea is, of course, the lack of predictability, and not being to have items in a fixed location, allowing muscle memory to form.
