>A lot of people have iPhones and many these days now have Macs.
Not really here in Germany. iOS has about 20% of the market, Android the other 80%.
macOS is at about 8%.
Anecdotally, even discounting that I have neither, of the 20 or so people I'd realistically want to chat with (friends and family), two have iPhones and one has a mac.
Plus: What happens when they switch? Or when I want to switch?
Also, I don't really want to use multiple applications.
In the US, many people have the iPhones and iPads. For professionals worldwide at least in developed countries, it makes sense to use iPhones which are far, far more secure than Android platforms, especially when taking into account total cost of ownership, the monthly fee for cell service on a high quality network.
In professional settings, the Mac is becoming a more popular platform, IBM is converting many Thinkpads over to Macs.
Many in Europe, even the young, smoke cigarettes which are very costly with the taxes. I'd suggest for both health reasons and using money for better purposes to quit smoking cigarettes and use the money for iPhones (and Macs).
A pack of Marlboros in Germany is about $8 per pack according to Wikipedia.
My daily cost for being on the Verizon (top cell provider, esp in NYC) network and having Verizon yearly upgrade for latest iPhone is $5 per day. Upgrading to latest MacBook 15" Pro from recent model is about $2 to $3 per day.
The Macs, iPhones, and iPads play much better together as an ecosystem.
