I think tiling would greatly improve the usability. If windows had tiling and something like dmenu I would be much happier. The start screen sucks, especially if you have a lot of applications that you commonly use. It's impractical to look for a application in the tiles. I know that you can go to the start screen and start typing in the name of the program (sort of like dmenu), but why should you have to go to a pointless screen to do so.

Exactly, and another problem of the start screen is that it's fullscreen - it's distracting when the whole screen changes.
