Are these calculators owned solely by Cambridge University students? I don't know, but I can say that I disagree with the previous reviewer's assessment of the calculator.
For anyone still using a scientific calculator without Casio's Visually Perfect Algebraic Method (V.P.A.M.) (or, I assume, the Sharp/Sony/etc. equivalent...) I would heartily recommend an upgrade. The ability to enter formulae and expressions just as you'd write them on paper (as opposed to in a bizarre order that makes sense only to a computer) greatly simplifies basic calculator functions and reduces the chance of errors. In addition, the fx-115W allows you to go back and edit the previously-calculated expression.
As you'd expect, the calculator features a full range of mathematical and statistical functions and short of full graphical functionality, I haven't found anything missing. Nine independent memories is enough for most series of calculations. Perhaps my favourite feature of this calculator is the CALC function - enter an expression containing up to nine wildcard letters and the calculator will prompt you to enter their values. If you need to repeat the same calculation with different numbers then, it's much faster than reentering the whole expression.
One other feature worth a mention is the two-way (solar and battery) power. I've owned this calculator for years without replacing the battery and the backup power means I'm never worried it'll die at the wrong moment.
In all, a very useful calculator that's served me well and that I have no complaints about!
