Back in the NeXT days, these development tools suite (Xcode, Interface Builder and WebObjects, etc) cost $50,000. Now $5. Unreal.
Don't know what Jobs was thinking.
Software makes or breaks a platform. If you own an OS like Nextstep, you're crying out for software. You don't charge $50,000 to develop on your platform.
And people wonder why NeXT failed.
