Most common calculators in the forum?

[jebem]

This is one of the most enjoyable threads i have been following in the past two years.

Some very interesting discussions, but only a few answers were correctly targeted at this thread title.
Therefore I believe the title should change to something more appropriate to the majority's replies, like "What and how many calculators do you own and why".

Please understand that this is not a criticism, just an observation of how the replies changed the original title focus.

As i said in one of my initial posts here, my calculator listing is too large and meaningless to be publushed here. Inventory listings can be interesting but that was not what was being asked in the title.

That said, my currently common used calculator as a member of this forum is the HP Prime.
Great software system, lots of useful features for pupils, students and engineers, and well built for a machine designed and manufactured in the 2010 decade.
Is it perfect? Well, no.
Show me a single piece of human made machinery that sports such attribute.
