but in the phone comparison thread PCMag was android fanboys?
ICS apps can work on gingerbread and honeycomb. There isn't enough tablet devices around where developers will have to concentrate on 3 versions, and again, an ICS app will work fine on honeycomb anyway. The developers can make 1 version, using the "pane" layout that google has provided, and it works across devices.
The second section boils down to the same thing above. One app can work across all devices and screen sizes if its built that way. So, a phone app can definitely work on a tablet, as its going to look different when it see's that its on a tablet.

Thats what he means when he says a phone app can work for a tablet
