Man, I love this thing. Really, except for graphing, it does just about everything my TI graphing calculators did...and then some. It can display input and answers in fractions (which comes in handy for me these days). The display for radicals is a lot clearer than I've had in the past. Like the graphing caluclators, it has multiple lines so you can easily visualize where you've been if you must do a progression of calculations. It gives true values for irrational numbers if you want. That is, it displays "pi" as "pi" - not the APPROXIMATION of pi as 3.14whateverwhateverwhatever or "1 + radical 5" as "1 + radical 5" which is more correct than some decimal approximataion of 1 + radical 5 (though you can shift mode, and have it calcualate that if you like). And to top it all off, it's lightweight, and I don't have to buy batteries for it because it's solar powered. But the best part is I stumbled across it during an emergency stop at Rite Aid for some unrelated item last week, and it cost me less than 20 bucks! The timing was perfect because I was a few days away from blowing 100 bucks (or whatever they cost these days) on another graphing calculator.
