Top three calculators ?

[pier4r]

Nice thread!

In terms of use I would say:

- sharp el-506w , it is really handy for most of the simple problems (thanks to the double line display)
- casio 9860G / GII . As discovered in another thread (n1) the casio basic is pretty limited (but see also n2) but the calculator is like an extended version of the 506w, and I love the keyboard. For little programs that the 506w cannot do, it is great.
- hp50g. The RPL is just extra versatile.
- Prime. Rarely, if the problem cannot wait.

On the android phone (not tablet, the tablets have the prime).

- handy calc
- n-calc
- free42

- n calc is the closer to the 506w. If someone knows something better like a 506w, I am interested.
