S1's do NOT need cgminer, they have built-in controller which you configure by browing to its ip address. You need to read more. By the way, S1's are outdated at this point, no matter how many you have. Sell them on eBay and buy S2's from now on.
Check one of the tutorials on the forms on how to setup. Everything will be in there.
Not everyone has $3000 to dish out on a miner.
So NO s1's are not out dated and will not be for quite some time
