Why would you tell someone that they'd waste their time learning how to code?
I said no such thing. What I meant was if someone has never done ANY programming whatsoever, starting off with the iPhone's SDK is probably not the best place to start.
A large percentage of those who downloaded the iPhone SDK didn't even take the time to check the minimum system requirements for the SDK - which IMO indicates a lack of paying attention to detail which is somewhat important for a programmer. And some downloaded the SDK without any idea what it is or for, or thinking they would have access to firmware update 2.0 for their iPhone now or something.
