It's the same problem with a lot of different programs one might chose to use, though math software is somehow particular bad for some reason, due to the high price for the non-student versions. It's always really amazed me that Maple academic is over $550 and non-academic is over $2000. Isn't that nearly an order of magnitude worse than non-student versions of Word/Photoshop/etc? One problem I personally had wasn't the same sort of forced transition from CAS X to CAS Y like you had, but that the sole "CAS" I could use was Magma, since it was literally the only program out there capable of doing pretty much any of the interesting computational mathematics I need for my teaching or research. Not only were all my eggs in one basket, so to speak, but buying a single license of Magma costs well over $1000, and that is *with* the academic discount. That situation was just very frustrating for me, not because I couldn't get Magma (I got it for free as a developer), but that so many other students and colleagues couldn't get it. Also, I think the technology in Magma overall is not up to snuff compared to what I saw as possible, and that situation is not changing. (I mean that Magma's capabilities in graphics, Cython-like compilation, user defined types, viewing of source code, etc., are poor.) There was just no rational choice but to switch. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
