Is the Prime the fastest calculator ever made?

[pier4r]

So, it always depends on what activity one performs with the tool (a calculator in this case). Though for the little summation test setup in this thread: http://www.hpmuseum.org/forum/thread-9750.html so far the prime is impressive!

The newRPL and the dm42 are impressive as well.

Surely I think that with some optimizations (es: nspire running lua, hpgcc on the 50g and so on) one could beat the prime, but realistically in all day usage one use the common functions, not the optimized ones. Therefore for common usage the prime is really fast so far.
