Im currently using the older 256mb model B version. I really like the less power consumption.
Lots of new updrages. I would imagine they will keep upgrading them and keeping it at the same price
as technology will allow. I heard rumors of a super raspberry pi . I dont know if or when that will come out.
The 1.2a output was a nice bump since the older ones could only do 200ma, which as others have said will allow for less
things to be connected.
