Mobile devices have a tremendous ability to hijack the functions of other more dedicated devices. A graphing calculator is certainly one of them. Purchased on its own, it is easily worth ~$100, but can be had for much less with a handy app, and less things to clutter your workspace.

The size of the Tab would make these apps simply FANTASTIC to use. Large buttons, and a detailed view would be key to higher productivity and greater enjoyment.

While the showing is impressive, these calculators may still lack the features of a dedicated device. Of course, there's also TI graphing calculator emulators which should mirror popular functionality minus a touch-screen UI.
