Seriously, I have a scary to do list but I finally got around to having a go with this the other day. It is very very nice. If you’re leaning towards a RaspPi and are interested in symbolic programming, it’s a pretty good place. Worth remembering that a RaspPi is not scary fast (ie, Mathematica on it is not hugely fast) but it comes across as something that a) is nice to work with and b) I will probably license on a bigger machine at some point.
