Take a look at this:
It LOOKS like an Arduino (but its not). Same basic Arduino feature set. (add a power switch and a little more neat stuff)
It runs ,,,,,, tada ,,,,,, BASIC! (Don't run, shake or shiver!)
(It looks one HECK of a lot like P-BASIC (STAMP 2) but has more commands and floating point.)
The editor can be downloaded and looks nice, but nothing special.
The manual looks nice and well organized and is BIG, but again is nothing special.
