Have a look at my Flickr stream to see what happened in between.

Now testing interaction between iPhone 4S and Arduino via Bluetooth Low Energy (BLE) using TI CC2540.

The housing, LCD, USB connectors make it a nice basis for both experiments as well as long lasting dedicated usage.

Not sure yet about whether to use a stock avr-libc program or even FreeRTOS, Femto OS or NutOS.
