Will the iphone 4s work for me?

I need something thats going to work decent for the next couples years at least. Someone told me they are not worth getting due to the new ones outdating it. Do y'all think it will be ok. I'm not a big app person. Ill just be using the texting, phone calling and camera mostly with some internet usage. Will it becoming outdated affect me really bad or will i be ok.

Definitely

For your limited basic usage, iPhone 4S will do just fine for next couple of years.
