⇨ Xcode 4

Interesting move from Apple for the release of Xcode 4: free for registered iOS and Mac developer and $4.99 / 3.99€ on the App Store.

On my spare time, I have been using the various beta releases of Xcode 4 for Mac/iOS development and I really enjoy the streamlined experience.

For Java development, I use eclipse that I know from the inside out after doing a lot of plug-in development some years ago. With every release, eclipse has become more powerful but also more complex and I have not noticed an increase in my productivity.

With Xcode 4 (single window, built-in Interface Builder, Git support with Time-Machine UI, iTunes-like status), Apple developers have managed to simplify the UI, streamline the experience and increase my productivity.
Kudos!
