Personally, I am a HUGE Android fan. The platform is solid, offers all that iPhone does and then some. I have used most types of smart phones in the past to include iPhone, Blackberry, Windows Phone, Palm and Android, and the Android devices have always been a big win for me. With 59% of the cellphone market now belonging to Android, the others will have a tough time gaining that ground back.
One last thing... check out Google's 'Project Glass'. This is a concept that they have been working on which is a wearable device that I am already prepared to empty my wallet on.
