"$10 for a poopy add-on?"
Yes, I said "poopy". It is a shame that math authors can't follow in their predecessors' footsteps. However, the good old DOS programs are still available for those of us smart enough not to upgrade to Winblows XPeepee! So, we don't need these stupid new Winblows add-ons and these greedy young copycats and Bill Fakes can go broke and die for their useless efforts! Yes!!! Hooray for the marketplace!
