I fell for it and bought the MAX32. To me it is just another development board. The arduino "form factor" means very little to me. Both boards have the same advantage that the arduino has. You can program using arduino libraries, or you can program using native code for the chip. They both have their strengths, and areas of use. It doesn't mean I will go out and sell all my Arduinos and AVR chips. I will continue integrating various AVR mcus im the projects that they are right for. Maybe someday I will integrate a PIC32MX chip in a project, if that is what the project demands. More choices for the consumer are good. The fact that they want to use the arduino libraries can only mean the arduino team is doing a great job!
