My opinion is that "--help" is usually enough.
With the small display of the pandora you don't want to have multi-page man pages anyway (Unless you like to work with lots of workspaces, as switching terminals is not possible using the normal keyboard) and a lot of users probably don't even use the terminal, and if, they will just live with "--help" or follow instructions on the internet.
Additionally one can still see manpages on the internet or install them manually.
For packages which depend on the manpages (and those should be RARE - but they exist, ptor gave the sample "git help commit"), they are probably included in the package, "--help" gives enough info or they have some fallback to a minimalistic description
Additionally, those who use the terminal from time to time, know those commands they work with and don't even need manpages. So unless you are working with TONS of different commands in which case you can't remember all switches etc, you wouldn't really need a manpage neither (And even then, "--help" would be enough to remind you of the available switches)
