I want to get a Nexus 4 as an upgrade from my iPhone 4 but I also have an iPad 3 that I'm not willing to give up. Is it difficult using two different OS's? Basically due to the patent wars, I'm afraid that pinch to zoom and double tap to zoom will be phased out on Android soon since that was a patent in dispute in the Samsung/Apple lawsuits in the U.S. Also, I read that Jellybean (Android 4.2) will have triple-tap to zoom in Gmail and two finger panning. I'm afraid that'll cause a lot of confusion and frustration since Apple (and my iPad) will still be double tap to zoom and one finger panning. I'm by no means a tech newbie but these things seem like they'd be confusing to any user. It's like trying to use both a PC and a Mac at the same time, something I often do with my iPad/iPhone combo.
