The Shield portable is a goofy looking PoS that you can't easily put into a pocket. For $200 the Nintendo or Sony options are a lot nicer.

The barrier to entry for Android gaming is lower, but no one is going to develop for the form factor if the unit isn't going to be in a lot of people's hands.

So instead we get games designed for touch that can optionally controlled with a traditional controller. Maybe.

The games brought to Sony Vita and Nintendo xDS have higher budgets and teams targeting the features of the console, so they sell even though the cost is high.

And touch is a pretty shitty input modality for anything beyond puzzle games.
