I found an iOS app that is basically a near perfect clone of the TI-83 (GraphNCalc83). I use that nostalgic mf nearly every day for the most basic stuff.
Used to have one for Android called Andy-83, but it was so good that TI took notice and threatened litigation. Though I still love the tactile response of the physical buttons on the real thing. Plus its a good place to find some AAA batteries when I need them.
