Here's hoping more developers follow suite and Microsoft is eventually forced to drop this whole failed experiment. The changes coming to Win8.1 and the terrible sales figures as people stick to Win7 are hopefully very good indicators that this will happen - and then the rest of us can get back to actually using an OS and not fighting it.
Metro is going to work out well eventually, maybe in Windows 9. Microsoft are playing for the long term here. When you use it on a touchscreen it really makes sense, and one day all screens will be touchscreens.
Yes all screens will eventually be touch screens, but as Nursie said below, touch will probably never be the primary input medium for any productivity task.
For one, it's much too slow because you have to cover the whole screen to interact with it. The mouse operates on a translation of the screen that is much smaller, making moves much faster.
For two, I sit over a meter and a half from my screen and couldn't touch it without standing up.
I would prefere to keep metro as the more "consumer friendly" ui solution and then REALLY improve the desktop so it can fight evenly with the linux ones and become really the place for us "pro" user who need to get shits done
