Why can’t anyone make them compatible?

I confess that I am old enough to know that calculators were invented, or at least on the market, before digital phones. And I ask the question, “does it mean that digital phones are to blame for not following the stupidity of calculators or calculators to blame for being so stupid in the first place?”

I seem to recall that an inventor called David Sinclair designed the first electronic, hand held calculator for mass consumption. Plenty of people think that he’s pretty smart. I mean he was the top guy in MENSA, the high IQ association.

So why, I ask this because I really want to know, did he layout the numbers in such a strange format?

This is how they were, and still are today, laid out on a calculator:

And this seemed logical?

Then we had a few years to learn this layout before someone invented and mass produced digital phones, which are laid out like this:

If you ever wondered why you mis-dial so often, or get confused when using a calculator – this is why.

And it’s worse because now mobile phones have calculators on them! So when you use your phone as a calculator the numbers are in a completely different place to when you use your calculator.

Please can someone stop this stupidity and produce a calculator that is laid out in the same way as a phone!
