Windows 8 Start UI was designed to take advantage of this. Theoretically it was great: when you open start menu the mouse pointer is in the bottom left corner, tiles close to you are wide and tall, tiles far from the pointer are smaller, wider at the bottom, narrower at the top. Hot corners were supposed to be easily accessible (infinite distance). Yet is was a failure, because uses were not familiar with it, it broke their habits.

The whole problem with the tiles is that they are much too big. Bigger targets are easier to click, but targets farther away are again harder to click. The targets in the start menu were plenty big to start with anyways.
