How Apple Should Display iPhone Apps on the iPad by mjdave
While I don’t at-once agree with the implementation (adding a thick black border to apps without iPad versions), I completely agree with the notion that there needs to be a visual indicator to help distinguish the different app types. I find the pixel-doubled apps trying to use on the iPad and would rather stick with the iPhone versions.
This issue might become moot when iPhone OS 4.0 is released, as I intend to stick the iPhone apps into their own folders on a separate page.
