Nah, RaspPi's are cool.Although they look like an Arduino on steroids, they are a completely different animal. I do not enjoy programming a Pi.
They're kinda like the opposite of Raspberry Pi - smaller than an Arduino. They come on a 8 pin chip, or you can get them on a board with usb. They have 5 and a half* io pins, 2 with pwm and 3 with ADC.* half pin is shared with reset.
