Way better than the TI-84 Plus CE; I also really like the UI since I also really like the TI-86 UI. Brother damaged it -_- |

Bought off E-Bay from someone listing it as a TI-86. For sure paid less than I otherwise would have, given that it's in almost perfect condition. |

Second Christmas calculator. Really nice to use, and I've convinced a number of classmates going into various fields in college where it might help to buy one. I hate how often it crashes. |

This is actually my second TI-84 Plus CE. My first one was an early revision, but was washed out after the teachers required we leave our stuff outside during a tornado watch. |

First calculator I bought for collections' sake, rather than to use. I do find programming for it fun and have written my own statistics suite for it. I also intend to, at some point, look at some assembly programming to add arbitrary x-value calculation for the graph math features. |

A very clear predecessor to the TI-86, and while it's missing a lot of what I like about the '-86, it's still very nice, and it has the boxy TI-81/82 shell that I like for some reason. |

Worse condition than the other one, but since I'd rather have that one, and can't return this one, even though the other one was supposed to be a regular -73, I have two 73Es. |
