I have had an iphone for 2 years now and I made the switch to android after 4 years of having a phone in total. I was on vacation and I was going to sit in a pool lounge chair and my knee fell through the crack between the leather straps with my phone face first in my palm. My 4s was totaled and I didn't want to get a iphone 5 a month before the new one came out so I made the switch. I am now the proud new owner of a galaxy s4. I am still getting used to it. Even with simple things I have to get used to, even the keyboard. It is so big (that's what she said). I like a little flame war inspired mayhem so let your opinions be free. What is your favorite type of os? Android, iPhone or Windows Phone?
