iPad mini vs iPod touch 5g for developing I want to develop for iOS and I want to do some real testing of my apps on the cheapest device.

Looking at the hardware they are the same except for the screen. They are both IPS but the iPod has a retina resolution.

Here are my concerns: with the iPod touch I'm sure that my apps will run well on the iPhone 5, with the iPad mini I don't know if it will be fit to test for the Retina displays in both the 4th Gen iPad and iPhone 5.

Will one of them be better for testing apps?
I think it makes sense to go for the iPad mini. This is because you can simultaneously test both iPhone AND iPad apps. The iPad mini will run iPhone-only apps in a reduced-screen screen mode, and will run iPad apps as normal. An iPod touch will only run iPhone-specific apps.
