"The main differences between the B+ and the Raspberry Pi model B are the new model has: - four USB ports (versus two in the model B) - a microSD card (versus a full size SD card in model B) - a video jack integrated with the audio jack (versus two separate jacks in the model B) - GPIO pins extended to 40 pins (versus 26 pins in the model B) - lower power consumption - four mounting holes What has not changed: - The price, it is $35 USD - The amount of RAM, it has 512 Mb" -- source: http://opensource.com/life/14/10/reviewing-new-raspberry-pi-b-board All in all, sounds like very reasonable changes - especially the 4 USB ports. Though would have preferred 1GB of RAM. :-) Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
