Still can do more on it easily and sometime quicker. You can do the usual gps, Internet, music, videos, make calls, an also do obd diagnostics, satellite radio, games if you were so inclined lol. I'm sure I'm missing a few but mostly its just what you want to do and ease of use. Sure a smartphone will do most of that but sometimes with more effort and a car pc is molded right on your dash so it's also easier to look at than a phone is.
