In addition to all the other things mentioned here,
I like that it's a global phone now, too.
Went to Italy back in May and had to rent an Incredible 2 from VZW because my Original Droid wouldn't cut it there. When I got the SGS3 in July I was hopeful that by the next time we traveled to Europe (hopefully by this coming summer) I'd be able to use it there without having to resort to another rental phone.
