Yes, let's keep this civil. ;-)

I have an old HP48SX, with a "POLY" library installed. To factor any
non-symbolic polynomial, I just enter a list which contains the
coefficients, ie, to solve x^2 + 2x+ 1 = 0, I use
1: { 1 2 1 }
ROOTS, which returns
1: {{ -1 -1 }}
this is very fast!

Does WYSIWYG make sense for a calc? The only times I use it on
the '48 is when I'm using a function I don't remember the parameter
order for (sum, integral).
Symbolic manipulations are very useful, indeed, but I think the power
of Maple is the minimum needed for them to be useful. How does the TI
compare?
Of course, I like UNIX and CLI's, not Windows and GUI's.
