Except the GNex still has a lower pixels per inch than the iPhone so doesn't that actually mean the text/images will be a little bigger?
This would only be true if smartphones standardized everything based on pixels like PCs do, but they don't. Well, Android doesn't, at least. iOS might, but that's because they're much more standardized when it comes to device resolutions The Android OS, on the other hand, was built with resolution-independence in mind, and it gives devs the tools to work with this.
Android phones account for both screen size and PPI so anybody building apps according to the specs laid out in the Android SDK can count on text appearing at a readable size and resolution on any device. I've been playing with a Rezound for the last two weeks and so far every app except Epicurious has worked perfectly. (I'd be willing to bet that that's because the Epicurious devs ignored the standard Android UI widgets and tried to make the app look exactly like the iOS version.) Images on the screen are physically the same size as they were on my previous phone, only now they're much sharper.
So no, getting a higher resolution doesn't make your text smaller, nor does it necessarily allow you to see more on the screen. Spatially, everything is about the same, only sharper. Of course, you can always pinch to zoom in or out and get things looking exactly the way you want, and if you have good eyes, a 720p phone will allow you to zoom out further than you could on a lower res phone. If you MUST have a quantifiable comparison to the iPhone, then yes, because of a higher pixel resolution, if you were to zoom out until the text is as small as possible before becoming unreadable, then you will be able to see slightly more information on the screen than the iPhone can. But that's just a ridiculous fringe case, as that would be horrible on your eyes. Any phone with 300+ PPI is a great screen.
The fact is, both the iPhones and the 720P androids are so high res that i doubt they'll ever significantly increase the resolution again.
