The S3 has a slightly better battery life and that seems to be the most attractive feature; but for 50% less $$ for this S2

It works great and has many neat features and settings

It is very simple to use and fun to play with all it's cool features

The dust rating is 6 (highest level of protection), and the water resistance rating is 7 (water-resistant up to 1 meter for up to 30 minutes)".If you don't have a Samsung phone, all the features may not be available to you

I've had it two weeks at this writing, and everything works as it's supposed to
