I had a few stumbles, but I'm super stoked with the MSP430! Bootloader from the factory, Energia, no BS in circuit implementation; I've made the switch!
My first project is a solenoid valve controller. It's for a rock crusher; if the crusher jams the 43oh briefly reverses the hydraulic flow to clear the jam. It can also be used to run a log spliter back and forth without needing a kick off valve and without needing to manually start the forward stroke after each log. http://arduinoforgoodnotevil.blogspot.ca/2013/05/launchpad-msp430-hydraulic-auto-reverse.html
