#11 It's a frickin' tricorder
You can download a free app called WeatherSignal that provides measurements including temperature, light, humidity, pressure, acceleration, and even magnetic flux (measured in microteslas).
While there's some useful information to be gained by all these sensor readings, one thing I learned is that there's one heck of a lot of magnetic flux within a few feet of my big server. It's a good thing I don't sit in front of it all day. Fortunately, the Inverse Square Law applies, so my desk (which is about six feet away) has almost no measurable flux (unless, of course, I exceed 88 miles per hour).
Once again, the iPhone can't do this.

#12 It supports near field communications (NFC)
NFC was supposed to be the gateway drug to easier credit card payments, but this hasn't happened yet. The carriers are getting in the way (as usual) and some users claim Verizon has disabled Google Wallet.
Even so, you can use NFC for some hacky activities, like triggering Tasker events (more about Tasker later) when placing your phone down on NFC stickers like these made by AndyTags (who explains NFC quite well). There are also a few substitute passbook apps, like the one from Attidomobile pictured above.
While NFC might well be a technology in search of a solution, my Android phone has it and my iPhone didn't.Image courtesy Attido Mobile.
#13 It has an IR emitter
Apple has long offered the ability to control your Apple TV with your iPhone over WiFi. But if you want to control any other device in your entertainment center, you've been out of luck.
Not anymore. My new Android phone has an infrared emitter, which effectively turns the phone into a universal remote.Image courtesy Touchsquid Technologies.
