I think one large difference between Maple and most other CAS
is that Maple accepts as "canonical" polynomial orderings
that most other CAS don't. Personally, I find looking at
a Maple univariate polynomial result an eye-sore. I believe
there is a no way that a user can request that all of Maple's
displayed results be automatically humanely ordered. I think
such an option would be worth the time spent.
