I have just bought a few RPi3B's to play with, they do seem to be available this year at launch which is a nice change. Stated current requirements seems to have crept up to 2.5A @ 5V1, so I had to buy something a bit beefier than old cellphone micro-usb chargers, just in case we're not talking about 2500mA 'fully loaded'.
Last year, whilst training people on Linux SBC programming & e-mail security, it was quite nice to see the look on their face when told that after a few days of training on this small PC that they could actually take it home with them (leaving the keyboards & monitors)
Maybe the new Pi will be able to reliably decrypt Proton Mail messages, the Pi2 was a bit marginal. . .
