I have an iPhone, but I also have an Asus Android tablet. I find advantages and flaws in both, and I use each device to its own strengths.
I also need to say that I was recently in an Apple store and found the iPad mini's screen to be very nice, much sharper than my Asus, but then again, the Asus was very cheap.
For casual browsing and making snide comments on facebook, it's perfectly fine. With a blutooth keyboard, it's even a nice SSH terminal. I don't do high-end computing on my tablet, and my phone is pretty much relegated to text messages, phone calls, photos, and the occasional need to access an app in an emergency. I'm not glued to my screen like most other people I know.
Android and iOS are both 'ok' -- neither is perfect, but frankly, the religious wars about operating system on your phone reminds me of the chatter between Atari users and Commodore users on Bulletin Board systems (showing my age here!).
