Re: Think of the users, and not just corporates
"The problem arises when your nice simple interface suddenly fails you when you want it to do something outside its simple features. The "just reads your mail and sends photos to your relatives" might then not be up to it when you're suddenly trying to organise a family wedding, a house move and a holiday all at the same time. At that point you realise that multiple folders with nesting, proper threading of messages and maybe a search function would actually be easier to use than the nice simple interface."
So Apple's native Mail app isn't quite so simple, as it manages all that if you want it to (though you don't have to use all that if you want it simple). I recall when MS introduced Outlook and removed its simple mail app of the time, I was annoyed - I liked the simple approach with separate apps for separate tasks. After a year or so, I got used to Outlook's integrated approach and liked it - just one app that let me link the various functions (mail, calendar, addresses and tasks) together. Heck, I even paid for an app to do something similar on my Palm PDA. Then, when the iPhone arrived and was able to join up hardware (for travelling, one iPhone and charger replacing a Nokia and charger, Palm PDA and charger, iPod and charger, GPS and charger) I tried it. But I had to revert to separate apps for mail, calendars, etc. I looked for an app that would link them back into one; back then, no luck, so I got used to the separate functions. As the OS got smarter, it's returned a good degree of integration and I now like having these functions separated. Apple's Calendar is good (for my uses) at being a calendar; Contacts is good as my address book; Mail does all I need for email (other than a few accounts where the Exchange login settings mean I need to use Outlook - those accounts have forwarding set so I can still use Mail's single inbox - I only need to fire up Outlook if I need to send from one of the Exchange addresses).
I have thought about switching my mail over to Outlook, since it would handle all my accounts, but I'd then lose the simplicity of Mail (and it's own integration with Calendar and Contacts apps (on my MacBook, iPhone and iPad). I'd also need to switch my wife over to Outlook in order to share - and one great bonus I found when she moved from Windows and Android to Apple was the regular calls to sort out a problem disappeared.
I help run digital skills workshops and drop-ins for the older folk in our county: whilst Windows predominates the laptop population, it's fairly even between Android and iOS with phones - but only a small percentage of phone help is in relation to the latter (and those tend more to be in relation to contract/SIM issues). My biggest issue is with family members who give an elderly relative a device (sometimes a cast-off, sometimes new) and then expect them to know how to use it. Millennials have grown up with the technology but boomers (and before) didn't and, for some, this is their first real hands-on exposure. At least Apple kit is fairly consistent in approach; not perfect but, in general, once explained for one context the skills transfer to far more. It's most noticeable when family decide to upgrade their elderly relative: iPhone 6S to iPhone 11 is not to great a difference (and the changes generally make things simpler); change from a Pixel to Samsung (or even a newer Android from the same family) and it starts to confuse (not a problem if you're comfortable with the tech, as people here are, but a different matter for an 80yo).
If my business was in domestic IT support, I'd despise Apple as it would all but kill demand :)
