I have, unfortunately, had to use Macs at various times, and I just never found the OS very intuitive to use. The iPad is built on the same Mac-style OS. A couple of Mac features don't make them unusable, but are extremely annoying to me: for example, the lack of a "Delete" button on Mac so you can only delete by backspacing, but you can't delete characters in front of the cursor. I don't know if current Macs still have that limitation, but my iPad does. Other elements of the OS just seem very cumbersome as compared to PC.
I see. Your “user-unfriendly” is my “just one of those differences” from a PC.
I agree that a Mac ought to have a “delete” key. I think it’s probably a matter of Apple pride, though. It would be a concession to Microsoft to add it.
