Is it worth getting the s4 or should I wait for the s5 to come out?
Worth is a very subjective word. If you want the Series 4 now, purchase it now. Unless you think you can wait, I’d say approximately six weeks or so, then you’ll know if there’s a new Series 5 debuting or not. By then, the Series 4 will be discounted if you’re not interested in what the Series 5 offers. So my opinion is to wait.
