As far as not doing much, I say the opposite. I have an app for Word/Excel file manipulation, MP3 player, calendar, games, sports apps, scan any barcode, GPS navigation, and much more.
I keep a Gmail account only for contacts and calendar updates to sync as necessary.
Understanding that a phone is not a laptop, I am not sure what more you can ask.
