I have now spent a pretty solid week writing applications for the iPhone. And what an exciting week it's been. I've been privileged to view and interact with the iPhone in a way that few other people have had the opportunity to. The iPhone is tight, robust and its SDK--even seen through such imperfect tools as class-dump--is beautiful.
Let me give you an example. This morning I decided to write a basic word processor for the iPhone. In about 30 lines of code, I was able to create an application that saved all changes to disk and reloaded that text launching the application. That kind of success doesn't happen because I'm some sort of phenomenal programmer, it happens because Apple makes amazing, usable libraries. I was able to use classic Cocoa strategies like reading a string to and from disk and combine it with new UIKit strategies like creating a keyboard that automatically knows how to enter and edit text.
