Free trials of un-tar? Installing apps that require subscriptions to the cloud? Dev libraries that require enterprise support packages?
Good package management on Linux is owed largely to the tireless voices such as Stallman who understand the core issues here. Yes, tying together install scripts and maintaining repositories requires a lot of work, and good for Microsoft. But the reason It Just Works is because the software is free, from top to bottom, including the OS. And Mac will have the same problem here as Windows. For now, I'm guessing this is just a command-line interface to app stores.
