1. Good for whom? Apple (who like money)? Schools and companies (who like locked-down, easy-to-manage systems)? Many (if not most) users (who like simplicity and reliability)?
2. When the Mac first came out, some PC users labeled it a "toy computer" and complained that it didn't offer access to the command line. It was a successful machine in spite of that (indeed probably because of that - Apple used the GUI for everything.)
3. For simplicity, reliability, and (perhaps) Apple revenue, Steve Jobs famously didn't want the Mac to have slots or even support memory upgrades (hmm, kind of like the M5.) Apple even made it hard to open without special tools (hmm, kind of like the iPhone and iPad.)
I think a worthwhile question to consider is: why does the iPad outsell the Mac?
Somehow I think that would not satisfy OP, but don't tell Apple about it. Oh wait, I think it's called a MacBook Air. (And I wouldn't be surprised to see future models with OLED touchscreens like the iPad.)
