Top three calculators ?

[jlind]

The current usage . . . subject to change without notice:

• DM42: the goto for straightforward number crunching involving anything transcendental for which the analyses have already been accomplished. It has displaced the TI-58 in this role.
• TI Voyage 200: very convenient CAS with larger screen than the "portrait" oriented LCD and QWERTY keyboard. A bit slower than the TI-89 Titanium with the same underlying architecture, but its screen size and keyboard more than compensate for it.
• HP Prime G2: rapidly taking over from the 50g for its sheer speed as I ramp up its learning curve. It's quite powerful, but definitely a different direction in practical use compared to the 48 and 50g that preceded it. Alternative to the TI Voyage 200 and preferred over the Nspire CX II CAS.
  

I still use others for quick four-banger number crunches and have a number of them laying about in various places to keep on in convenient reach. Using an HP Prime to add two numbers together to calculate price with S&H and sales tax, or divide them to compare price per unit volume or mass of different sizes of grocery packaging is overkill.
