It's very good for developing applications with high performance requirements (CPU/RAM).
We use it primarily to develop mobile apps which are deployed through iTunes Connect - we're using all of its features such as iAd integration etc., but there isn't much support other than what you can find online via forums or Stackoverflow questions asked by people who have similar experiences like us running into issues that aren't well documented anywhere else so far. The UI could be better designed overall; some things do look dated when compared side-by-side against newer tools out now even though those new ones weren't available at launch time either - this was also true about many aspects back then too! I'd say go ahead if your project requires complex graphics work or heavy processing needs because they provide excellent solutions across multiple platforms including iOS / Android development where others may not offer quite comparable feature.
