I've had my Nexus 7 for maybe like 2 (or 3) weeks now and I'm still wading through the Play Store. Unlike my daughter who has no qualms about installing whatever to try and then jettison it for something else (and thus populating "My Apps" at a prodigious rate ), I tend to do a bit more research- to the point of paralysis by analysis .
What I'm most interested in:
-Fitness tracker that uses GPS, doesn't require a constant data connection, and an easy UI. Currently using Google My Tracks.
-Email that will push Gmail and Outlook.com notifications but doesn't necessarily have to sync with either.
-And whatever else that you consider a "must have"
