Tuesday's news wasn't all about the developers. We're finally getting cut-and-paste. It's one of the things a lot of people have wanted most. It's a difficult user-interface problem to solve; tapping, dragging and other gestures already do something in most iPhone apps. The planned double-tap to bring up copy-and-paste tools might work, though I can see some problems in real-life use. You can't customize how quick or long a pause defines a double tap, so a lot of people may need to boost their finger dexterity.
Given that it will work across all apps and is built into the API set, we'll manage.
Also finally coming; MMS messaging; Exchange support in the iPhone's Calendar app; voice memos; CalDAV support; and Spotlight search. We'll have to see how well Spotlight adapts to the iPhone's UI and its memory/processor limitations; it already has enough UI trouble in the regular Mac OS X. But searching across your iPod content will be cool, even if you still can't ask it, "You know that song that goes like this?"
For the developers, 1,000 APIs. For users, 100 new features and countless new apps to come. Apple isn't just answering the desires of developers, though this update will do that in a lot of ways. It also shows that Apple has found the sweet spot of making its success dovetail with developers' success. Apple takes 30% from each App Store sale, so its own best interest is in opening up the creativity of the group mind. Everybody gets something cool, everybody profits.
What an insanely great idea.
