One of the things I like doing is taking an Arduino project and rewriting it without using the Arduino libraries, and the benefits go beyond complex problems like timing. It is possible to trim a lot of memory and flash usage if you are tailoring your code to a specific project. The end result is you can do more without purchasing and learning a new microcontroller.
