Unfortunately I don't have a lot of official details but there has been a bit of work on the power supply area and a linear regulator has been changed to a switching regulator and the power usage is meat to have dropped from ~750mA to ~600mA. It will be interesting to see if they have stabilised things a bit when using certain USB devices.
I don't have my hands on one yet but when I do which should be late this week hopefully I'll be able to to some tests on my bench.
I would prefer a Model C that was more powerful, had increased bandwidth for the USB ports (USB 3.0), and Gbps ethernet. While the layout looks improved it still has the issues of low bandwidth for it's USB ports and 10/100 ethernet.
Yep I still think for what they cost, and what you can do with them, they are an amazing piece of kit. I have 5 in operation currently, 2xRaspbmc clients, 1xIrrigation controller (using 4xrelay board and MQTT) which includes the camera module for keeping an eye on things in my garage, 1xBackup server which has a ready-to-go install containing dnsmasq and Freeswitch in case my main server goes down, and one for tinkering - which currently happens to be voice recognition/control via Jasper.
Will be interesting to see what people can do with this B+ version and if it offers much of an improvement in any area...
Usable USB ports will be a huge bonus. Getting the number of sides that cables go into down to 2 is a huge improvement. Stickey out SD being removed. All positive. Removing the stupid pointless RCA socket too. Hope they use the board as a basis for a new model A as well, since removing the analog jacks to get the size down is a bit hard on a board like that.
I should get some old models ordered before too long, as I have a couple of half finished projects I have pillaged the pi from to do something else with and dont want to have to re-glue the standoffs to hold it etc.
