My Samsung Note is nice, because the screen is big enough to actually see.
The new Note 2 is equally impressive and much faster.
That being said, I spend much of my time very far from data sources. I never leave home without the maps for the day loaded onto my Garmin eTrex 20.
Moreover I never leave home without hard maps anymore either.
