Do you need the best, or will good enough be good enough? I ask because I suspect, like cameras, the best computer algebra system is the one you have with you.

Do you need the best, or will good enough be good enough? I ask because I suspect, like cameras, the best computer algebra system is the one you have with you...or rather what matters is using one not shopping for one.
