The list of the reasons why Android is better than iPhone (as of April 2012, anyway) could fill a book.
1. More secure screen lock - pattern lock has 389K combinations, vs 10K for the iPhone
2. LED notification light - I can customize the light color for different notifications and know exactly what is waiting for me without having to turn on the screen.
Missed call/voicemail? Green light.
Text/Facebook message? Blue light.
WhatsApp message? White light.
Low battery? Red light.
4. 4G LTE - 12Mbps up, 10Mbps down, 38ms ping, all day every day.
5. Free wireless tethering
6. Widgets
7. Google Navigation
8. Firefox/Chrome-to-Phone - Push a website (to the browser), directions (to Google maps), phone number (to the Dialer), or text (to the clipboard) from my PC instantly to my Android's screen.
9. Ability to change default programs/choose from multiple programs to perform a task
1. Moot point. 10k or 1 million. Someone has to have physical control of your device, and you can remote wipe your iphone should you wish it.
2. Not all new Android phones have LED for notifications. My Skyrocket does not, as a matter of fact. It is an awesome feature though and my next phone will def have it. But until all manufacturers and android phones have this feature, you really can't give the Android OS and edge over iOS.
3. You apparently missed this number in your counting.
4. LTE will only be an advantage for Android based phones for a few more months, and then if we go off the rumors, BIG IF, the iPhone 5 will have a bigger battery to give it the same battery life as the ip4, but retain the same thickness. I have put a larger battery, same physical size as the stock battery, into my Skyrocket (2250mA vice 1850mA) and it now gives me roughly the same battery life as an iPhone 4, but that doesn't come stock. And not enough places have LTE yet to call it a standard feature. I am currently in Apple's backyard (Palo Alto, CA) and LTE here is spotty. One side of the Hillsdale mall has it, while the other doesn't!
5 and 6. Free tethering is good. Advantage to Android phones. Widgets isn't an advantage. They are battery hogs. I only use them to keep my RAM in check on my phone. I have weather and battery status on my notification bar.
7. Google Nav: big advantage to Android OS over iOS! You can buy a GPS nav for iphone though that will have more features, like speed info. Still, I really, really love Google Nav!
8. Firefox and Chrome are both crap on Android! Don't even try and pretend either of those browsers are good. Dolphin and Boat are both better. But being able to add a contact from any site, email or text is awesome. My hope is that Chrome and Firefox get better over time.
9. Meh.
