For me, the loss of 32-bit app compatibility could potentially be both a major hassle and a significant expense. A hassle in part because there are several small utility apps I use which are 32-bit only. All are old, and the developers have long since lost interest in updating them, so I’m going to need to find suitable alternatives… And yes, I’ve had plenty of notice, so could have done this by now, but they are apps I run perhaps once a month – so I haven’t prioritized them.
