I don't argue that games are a good way to kill some time (I play angry birds myself every so often) - what I find incredible is that people are making as much money as they are, selling games for these platforms. I don't know if any other class of apps are making as much money on these devices as games are - and that disturbs/disappoints me.

Games are appealing to about the widest possible audience. Everybody likes playing games, not everybody is productive in the same way, or works in the same way, etc.
