when 128k is not enough

THE OTHER OPTION
arduino mega 2650 :- 256k flash 8k ram 4k eeprom ,the sainsmart clones <$20 delivered .
big bonus 16mhz mega is about 4 times faster at floats than a 64mhz pic18 and equal or better at most other tasks, plus the free compiler is outstanding , especially in its optimisation capabilities .
floats are pain free in comparison to the microchip float library. its almost as if atmel actually want you to use their products unlike others who want $1000 for a decent optimising compiler.
most of the free libraries I have tried are very good even the colour touch screen glcd lib (try to find a free one that works for a pic), there are bigger/faster models too including a 32bit version that looks to be using the same ide . got one of these (a mega)plugged into the pi too via rs232
ps debugging
wow for $25 got the atmel studio arduino suite plugin , source level debugging at last that actually works and without any fancy (expensive ) headers either

the arduino forum has about a 100 new posts a day compared too ??
