Played with the Photon. I'm hooked! The over-the-air reprogramming is worth the price of admission. Obviously it doesn't have all the libraries that the Arduino's do, but the main ones are there. Thanks to Gelicia (aka K) for the pointers!
Got some ideas on what to bring for the speaker enclosure. Got some ideas for the MP3 player. Got some ideas for additional LEDs. Now to research how to set-up the Jukebox website and Tweet feed. Probably more help calls into Gelicia!
