OS X command line user here, after testing various other 'nix distros in the past few years. You're a bit harsh on the topic. Sure, composability is awesome for the reasons you mentioned, but look at who's using iOS devices. Do they need more? There are days when after being bombarded with information, an app that does one thing is a breath of fresh air. "But it’s not a computer, it’s just a glorified palm pilot with a few bells and whistles". You can SSH into it if you want to be hardcore ;) When I'm using an app to track expensese while at the supermarket or taking notes while on the train, I really don't care about "composability". Why should I?
