I was seriously dissapointed in the raspberry pi. The price is good, but that is about it. It order to get it running, I had to purchase the folowing: HDMI capable monitor ($120, I have plenty of old monitors that take VGA, but none that take DVI/HDMI), usb mouse and usb keyboard ($40, same issue, all my old mice and keyboards are PS2), power supply, case, and memory card. That actual cost of that little $35 board was was well over $200. True, this board will require much of the same hardware, and will cost well over $400 to actually get it up and running. So in reality, it is about twice as expesive as the pi.
Once I got the pi up and going, I realized that much of the marketing hype about being an 'open' development platform for learning about computers was total garbage. You cannot get a schematic of the board, you cannot get the complete spec. sheet for the processor nor can you get much of the source code. It was not the product that I had hoped it was.
