I found tiles a great ideas on Phone (I owned some WP and developed apps for it) but always hated it on desktop. The ever moving parts were making difficult to find information by catching the user attention. Also the 2D layout also posed a problem to scan entries, especially as most were cut after a few characters. That was a pain to found the good Visual Studio command prompt for example.

And now some of the Win8 area remains such as wierd black squared background behind software icon.
