Tough question to answer so soon. For still basically being in beta the eos.io software is surprisingly good. Because it's under heavy constant development, I wasn't expecting things to go so smoothly. I have never encountered an issue I couldn't work out. There are a few noticeable kinks that are already fixed for the next planned beta release (dawn-3.0), but no show stoppers. It can take a long time to fully understand the entire framework (I am far from the complete understanding) and if you don't already know a bit c++ I can see it being difficult for new developers. However the software is extremely powerful and provides the necessary tools for utilizing decentralized computing. There are lots of things you can do. Furthermore, if this project is successful, I can see other dev tools being made around it to speed up development.
