On Friday in Calculus II, we were covering integrals which are generally done by looking at tables or solved using a CAS (computer algebra systems). The other 17 people in my class (though about 4 of them use HP scientific calculators) use the TI-89 as their primary calculator. I use my 49g+. So, we were working problems as a class, and so everyone was punching them into their calculator. My teacher (who really likes the HP calculators) would get the answer from the TI-89 first, and then from my 49g+. For every single one of the integrals we did, the 89 would return an answer which was several screens long (very very very large answers). My calculator would consistently return a 1 or 2 term answer. Everyone would ask, "How does it do that?!? My answer takes the whole board (literally), and his answer is tiny."

It was really quite funny. And I didn't even bring up the trying to add 1 to 1000! (to add 1 to a large number, it takes the 89 about 30 seconds... the 49g+ does it instantly)
