I think the machine that they design on isn't nearly as important as the machine that they have in their head as designing for.
When testing the early OS and apps for the iphone apple purposely cobbled together a machine that was crippled (performance wise) to be representative of how the end product would run from a user experience perspective.
No. They would write the kind of software we used to write back in the days when all computers are like that and we traded away everything else for machine efficiency because we had no choice: clumsy, feature impoverished, riddled with arbitrary limits that trip you up at the worst possible moment, fundamentally insecure, hard to use and generally crap.
