No wonder the Raspberry Pi Model B was on sale. The day after I bought mine, the Model B+ hit the streets, at the same price of $35. Same CPU, same memory, but the board layout is much nicer–cables come out of three sides now instead of all four, which makes placement much less awkward–and it now comes with four USB ports instead of just two, so you can connect a keyboard and mouse and still have ports available for other things without having to plug in a clunky USB hub.
It’s an incremental improvement, but there’s definitely the potential to build stuff with it that looks more refined than the predecessor. I’m sure I’ll use one on my next Raspberry Pi project, and there will be another one. If not 12.
