Am I the only one who thinks a 4 inch display on a smartphone is fine ?

I m planning to buy an iPhone 5s . I ve Been using Android recently and now I think these Android phones are just too big and unmanageable in day to day situations . I picked up an iPhone the other day found the size very appropriate . I have used iOS a lot on the ipad though . Do you think it ll be good buy ? (and yes cant wait for the iphone 6 want an iphone now)
