(More customer reviews)Compared it to casio 115es and the sharp 516w (both are top-of-the-line, non-graphing, non-programmable, scientific calculators). This thing blows them away. It is much easier to use. It doesn't need specials modes for matricies and complex numbers, and does them on the same stack (just like CAS calculators). The operation history is implemented just like on ti-89/92. Go up and grab any number from history, and use it in any calculation, by simply going up to it, and hitting "enter" (it's easier than copy and paste). They finally fixed the "*10^" problem and replaced with the standard "E" button (which takes priority over all other operations). It's as if they listened to all of my complaints about the ti30xpro and fixed them all and made the ti36xpro. All the extra features (solver, matrix, statistics, formula table, integrals, derivatives) are extremely intuitive, and I literally never needed the manual to use them.
Another AMAZING thing (because we're on AMAZon.com), is that after you solve for things in the solver, or you do the linear fit on your statistical data (as an example). The calculator actually saves the variables from their respective solvers into the variables. So after you've solved for things, all your solutions are in the variables. IE, you solved for t in the solver => go back to stack, and the variable t will have THE number in it. Calculator also remembers the history and the variables when turned off. It's intuitive and simple.
My only gripe is that when editing it defaults to the "replace" method, instead of "insert". I usually need to insert things when redoing calculations, not replace things. It's an extra keystroke, it's a minor gripe in comparison to how much easier it is to use than the competition on all other counts. Another small feature that I noticed on the Sharp 516 is that it puts apostrophes on the thousands (so it shows "1'000'000" instead of "1000000"), which is a nice feature for big numbers. This calculator doesn't do that, it's no biggie.
More on the competition. The method of "mode-switching" that all Japanese calculators are famous for, is antiquated. The casio and sharp calculators literally forget everything that was done in one mode and switches to the next. If you solve for something in one mode, forget about it, you have to write it down on paper, because switching modes deletes history, so there's no way to look over it in the calculator itself. Casio 115ES is "amazing" in that it forgets all history when turned off! Say you're doing your homework, walk away to grab a snack, come back, your calculator auto-turned-off, and all your calculations are GONE! "Genius"! The history on both sharp and casio is annoying, you can recalculate the formula from the history, but you can NOT use it in your current formula, and you also can't grab the answers to use in your current calculation. After using TI's implementation, this limitation is simply a cripple.
If you have any q's, let me know; I have all 3 calculators, though maybe not for long :). If you're used to cas/graphing calculators, and your teacher doesn't allow one, this IS the calculator to get. It has the most universal (no mode switching) history/stack system, and it has the best copy/paste method. I almost don't miss my ti92 on the chem tests :).
