i've only ever used an iphone for work. i've had android since before it was Android. had a blackberry prior.
i don't have a preference but like the customized ability to turn my ridiculously overpriced over technological device as basic as possible. no sounds, no fancy programs, nothing at all fancy. a browser, a camera, a text messaging device, a music streaming device, etc.
i keep getting android because i can make them last 5 years without a problem. iphone does not let you do that. they'll lag you after 2 years.
