Thanks for the replies! I will certainly not argue about the LCD vs OLED display differences.. They are vast from what I can tell. In my particular application I'd probably opt for LCD for longevity since the liquidware OLED displays have some issues with burn-in for certain colors (blue in particular) from what I've read on their site. I guess I like the fact that I don't need a full-blown OS for the arduino's like I would for the bigger boards besides the power hungry nature of them (the bigger boards). I'll revisit my options some more and check out the ppc 6700 option as well! Thanks all!
