What Jobs' engineers did ...
"Clear options and ease of use"
Ah, no. Not really. What Jobs - or rather the engineers working for him - did was give users "if you do things our way, they are easy". They did NOT give them "what you want to do? It's easy in our system!"
Flexibility is NOT a buzzword applicable to the iPhone or iPad (yes, yes. I do own both. You don't want to know what I have to do to play my ripped CDs.)
