Review on Open Watcom by Jason Epstein

I like that it has all the tools you need to write native code. It also supports multiple platforms such as Linux/Unix, Windows, MacOSX, Android etc. The documentation can be sometimes confusing but if you know what your doing it shouldn't be too hard to figure out how things work. There are some quirks with using certain libraries which can make debugging difficult at times. If you're looking for something that will allow you to build native applications without having to go through another IDE then this might not be the best choice. We were able to develop cross platform mobile apps very quickly. This allowed us to get our app into production faster than we would have otherwise been able to do so. Also being able to target both iOS and android devices was great!
