I recently published this concept imagining what Windows 9 alias Threshold might look and work like. Since then, much new info has been leaked, but I think the concept still holds up to all expectations and leaks.
The idea is that Microsoft should ditch the two-interface thing and instead create two very similar interfaces, one for mouse and one optimized for touch interactions. This concept only deals with the latter one, while changes to the traditional desktop are not part of the article. Nevertheless, I want to emphasize that the GUI in the concept is only intended for touch interactions, and that the desktop would definitely stay.
From the few feedback that I received up to now, the first impression is apparently rather negative, with especially the design and appearance of the interface being criticized. What I think is the core of this concept, however, is not the design, but the different mechanics and the way that the whole interface would work. I tried to make everything as clear as possible through the different pictures and mock-ups in the article. Also, I guess it would probably look significantly better in reality, outside of static pictures.
All in all, I think this UI could do a pretty good job at bringing the tablet experience much more close to the PC, and thus it would also yet again highlight Windows even more in between a tablet market currently dominated by Android and Apple devices.
What do you think about this concept? While Microsoft seems to be putting more focus on the desktop again with Windows 9, what might happen with tablets? Do you think the current basic navigation schemes, such as Charms and the Start Screen would at least stay for touch devices, or do you think Microsoft will start completely anew on tablets?
