Yeah, I'm not a big fan of that either, but this is a non-CAS $13 system after all.

I think the repeating decimals function is the major feature of this guy.

The Youtube video I mentioned in one post is very good, I am considering whether to use this calc with the students in my algebra class. I have not used any calculators in the last few years in my classes, but I very much like the idea of "let the students experiment and figure out the rule without me saying what the rule is".
