Summary: Exactly what an engineering student needs.
Comment: Having been in engineering classes when the first HP calculator came out that was heavy as a brick and had no "memory", this is an amazing calculator and exactly what my son needed for school. As a matter of fact, he had the choice of renting one for a semester and loved it so much that I got him one for his birthday! He is thrilled.

Summary: This is a Platinum!!!
Comment: This is a great calculator, especially for anyone taking caluculus courses or anything from there on. This has helped me through highschool all the way to college, great product and very reliable. HOWEVER, beware, this is NOT the regular TI-89, this is the Platinum version. I just ordered it thinking I would get the old version because I like the colors and design better (easier to read buttons), and the titanium version arrived yesterday. I dont think it is fair at all, considering I paid extra to get the old version, and from what I've seen, I threw away money by thinking that the product description was true... You might as well look for the titanium and buy that, save the extra money...FIVE stars for the calculator, ONE star to amazon for generating all this confusion....

Summary: WOW, an expensive load of garbage
Comment: I bought this like 3-4 years ago and have hardly used it, and it worked great when I needed it, but just recently 1 day suddenly entire rows of pixels started dying on me (literally they started vanishing in front of me). The bottom most row where u enter data is fine, but several rows above it have died. I contacted TI and those thugs ask for 81 bucks for repair or replacement with a reconditioned model. Heck I'd much rather spend 81 bucks and buy some other companies product. Never going back again to TI's garbage again unless I need it for some course of mine. If I can find some alternate I'll definitely take that.
