Not in order to have CAS, but rather to have a calc where the company dictates what we can do with it. That's an option, but it is more if he can't stand the restrictions that TI have put in the Nspire. I personally know that if I bought an Nspire and couldn't do anything I want with it, I would either get a refund from the store (which often works over here) or re-sell the calc then get a different or older model. Of course if he follows your suggestion then he can re-gain the ability to use nLaunchy, though. The $10 price tag for an adaptor depends of where he lives, though, because in Canada, shipping is sometimes twice the original item price, but it should hopefully be less money than re-selling the calc to buy another.
