Relative to a Nuvi, negatives for OSMand are:
- some goofy routing, due to wrong assumptions in osmand about how
long things take. Specifically:

treated at the default speed for that class, and usually you
can/shoudl only go half as fast on link roadsa[
In the US (at least) link roads have an 'advisory' max speed which can
be added to OpenStreetMap via the maxspeed:advisory tag [1]. Assuming
Osmand makes use of maxspeed:advisory then this might mean that editing
the link roads where you find an issue to add maxspeed:advisory into
OpenStreetMap could fix this issue for you.
The positives are:
- ability to have really up-to-date data via osmlive (vs maps updated
on the 10th, so with plain osmand your data is from 10 to 40 days
old, unless you don't bother to update -- still very fresh)
And further, ability to actually update the data yourself (via editing
OpenStreetMap where you find issues/missing data) and seeing the
changes appear in Osmand.
- not having to have a second device, assuming you'd have your phone
anyway. But you really need external power for any length of time.
The need for external power is universal. My old TomTom device also
needed its external power plug for any extended length of time as well.
