[Open Discussion] iPhone vs Android: Which do you use and why?

Back in the day I used to be an iPhone advocate. The last iPhone I got though was a 3gs. The reason I changed to android is that when the iPhone 4 came out I didn't like the shape and it made me realise that if I kept with Apple I would have to accept the style and technology that Apple would release. With Android not being constricted to one device, I could choose from style, hardware specifications, price etc. 

Don't get me wrong, Apple technology wise is always of high quality but with Android, especially now, you can get the same premium quality or if your budget does not afford that, a device that will work with all your other apps for a cheaper price.
