The Adventurer 2800 seems to be a contemporary of the Garmin Oregon 450, each a 2010 release or thereabouts, and that's the unit I have (thanks to a donation). I love it to bits. It's a workhorse. I can't speak for the MM range but the Garmin units can work for years on end.
One big advantage of a dedicated unit has is water resistance; my borrowed Android phone, full of fantastic GPS and outdoorsy apps (such as star maps), drowned in horizontal rain on Ben Lomond. And it was such a glorious, cloud-free sunny day in the carpark! Yes, now I know "ziplock bag", but that starts to make things fiddly.
Of course if you have a phone with a high waterproof rating this won't be as much of an issue.
