1. The majority of the games plainly suck. Seriously.
2. Touch screen controls. While I'm fine with it, you can't compare those with actual buttons. If you're talking about FPSs then it isn't even a contest, it's simply unplayable on touch screen devices.
3. Mobile games are much better on real consoles. I say that because most ports from games I don't like on mobile devices are great on consoles(Zenonia DS, for example).
