Honestly, I want to try and show this to my friends with 4S's, but then I realize it's not worth the trouble.
Rule #1: Never, EVER, show a cool Android feature to an iFan. No matter how awesome and useful it is, they will dismiss it as useless and unnecessary. Then when Apple inevitably steals it from Android, they will say it's awesome and revolutionary (notification bar, multi-tasking, voice to text, etc.). I've stopped discussing mobile technology with iFans completely. They lived in a walled garden and refuse to see the value in anything not Apple. Every once in a great while you'll run across an iPhone user that loves technology in general (like
the Woz) and enjoys talking about the pros and cons of all devices, but in general iPhone users are close minded sheep that think Apple can do no wrong.
I showed my new Gnex to my bro (an iPhone user) and told him the browser on the Gnex is actually faster than Safari on the iPhone (given equal data speeds). Later that evening we were trying to look up something on the net (guitar tabs), and he insisted that he do it because he could find it faster because the iPhone is "just easier to use". Nevermind all browsers basically function the same regardless of the OS, the Nexus has a bigger screen with a higher res, and I already told him it was faster. I beat him to it and we ended up viewing it on my phone anyway because we could see more of the page due to the high res of the Gnex.
Before the Gnex came along the iPhone had many advantages over an Android phone. Reliability, ease of use, better quality apps (I'm only counting apps that are both iOS and Android), more apps, performance, the beauty of the OS, better screen, etc. Now all it has is better quality apps and that is becoming less and less true these days. ICS+Gnex trumps iOS+iPhone in every other category.
