Sarcasm aside, I get what you're trying to say, but I'm not so worried. It's not like Apple's going to just bundle in every successful business, they're clearly targeting specific gross functionality which benefits from unification.
As an end user, I'm very glad there will now be a unified place for to-dos which any app developer can hook into. Cloud storage for all my apps? Cool. A glorified bookmark feature in a web browser? Shocking.
Even my local sandwich shop sells salads, chips and soda.
Now if any developer wants to build 'such-and-such' feature, the cloud is ready to sync that data.
Another example: Rich Text Edit: Lots of apps can use that one! I really like what Apple is doing to take care of building services that we can all use, vs. keeping behind some walled garden where we have to either pay to use it or build it ourselves.
Will you say you are now more concerned about startups (YC or not) which are building innovative apps for iOS?
