I think no one should buy apple anyway …
Irrelevant and inappropriate.
… but many people do …
I must be one of the people who have done what you think nobody should do,
and I am extremely happy that I did - and have done for a very long time -
because many people buy Apple, with good reason, not just for use for PD.
(And yes, I have also used Linux a lot, and have suffered MS Windows too.)
Many people also buy iPhones that integrate with their other Apple devices.
Many people enjoy OTHER software that only runs on Apple, not Linux or Windows.
Many people are happy to pay for it, too, if it saves them time and helps them earn money.
… and my problem is how to get to them ..
what you think other perfectly intelligent professionals should do.
