I have a Zumo 665, which is the biggest POS I've ever owned for a GPS, but I still use it because it's better suited to navigation than my phone. I hate the low-res maps and how slow the thing responds, but it's tough, waterproof, and works with gloves. I do still use my phone when stopped to doublecheck locations and routes, since it does have a nice high-res display, and I've downloaded tons of maps to it so I don't have to be in a coverage area.
Not the case for Samsung Amoled display. Big screen that not at all different than same GPS software screen.
Can't comment on iPhones thou. Yes, I do not like iPhone :)
Interface of Garmin on Android is same with interface of Garmin on Garmin.
Saying that - direct sunlight on Garmin 350 is no problem unlike Galaxy.
