Since a full version Mathematica is available on the Raspberry Pi, anyone who is interested has a very inexpensive route to getting a free copy. Mathematica is very functional on the Raspberry Pi and, I think, making the software available as such is very generous of Wolfram. Also for those who cant afford a Raspberry Pi, excellent mathematical functionality is available via the Wolfram Alpha website for free.

My experience is that they've significantly ratcheted down the amount of compute time per request in recent years. It's become much less useful to me because so many of my requests time out.
