How is the iPhone transition?

I currently have an iPhone 3gs that I love, but has just burned out. I've had it for a good while, but it is just too laggy and the camera doesn't seem to work. I really need a new phone. I love iPhones, but I'm not sure if I should go for a 4s or just stick to like a Galaxy s2 or something. I don't want to spend a ton of money on another phone. I just want to know if it I should go from an iPhone to an android or get a 4s. Would going from an iPhone to an android be a big transition? I'm not sure if I will get along with an android product. I need help.

Stick with the iPhone. Galaxies are hard to handle and are tricky. IPhone 4S is good for you

Stick with the iphone. You will find the android OS too difficult to use and you will end up switching back anyway. Trust me, android is not a good OS choice if you're not a tech geek.
