Not when your outlining a iPad mini using the same resolution as the original iPad. In that case there is no more work than is already involved.

Nothing stopping you doing your graphics at a higher resolution and working in that then scalling down.

Also the harder it gets then the less competition, which for you a developer has to be good if people are put of by having to design/do work.

I don't get the last point. It's a level playing field. If it's more work for other developers, it's more work for you too.

Last point being that if the person who write application has to do more work and effort then it will put more people off and as such mean more work for those who can be assed to do that extra little bit of work.
