The Note is pretty freaking big. At the same time..its kind of luxury feeling because of it. I have a galaxy nexus. I like it a lot, but its about the maximum size I could fit in my front pocket. The Note would be relegated to non pocket duty at all times, which would be inconvenient from me. I don't usually like to keep my phone in my back pocket.
Its a great phone. GS3 is great too. Just decide what size you like.
