Google Maps Places is nice... but really is no substitute to the purpose of Poynt.
Poynt will give you nearest gas stations based on best prices for particular fuel types. I don't see this in Places.
Poynt offers Reverse Phone Number lookup.
Poynt offers a much better UI for nearby theaters, nearby movies, Top 10 movies, and more.
Poynt provides restaurant/bar searching with more search engines than google places does (superpages, citysearch, and opentable).
And more.
At the same time... Google Places offers a few things that Poynt doesn't. Poynt integrates well with Google Maps and offers a slew of nice services from a simple UI. It's still new to Android, and I'm relatively confident it will grow and expand rapidly to the extent it won't be long before a lot of Android users are just as addicted to it as Berry users are.
