there is 16gigs of internal storage, but the amount available is not given on the box. Yes this is misleading, but they did not lie.
2.8gig's for installing apps makes me not care that another 5gigs is being used for Webtop. So all in all 8+gigs for video/pics/extra app content is more then enough. And like you I threw in my old 8gig SD and have the same amount of storage as my old Vibrant now, but I have more space for apps. So I'm a happy camper with that and the rest of the phone
When you see something go screeching across the floor, leap up and latch onto your friends neck you just have to laugh cause... what the hell is that thing.
Remember people, instructions are there to help you not hinder you and anytime you skip them you are doing the same with your phone as it would be to walk off a cliff with a self packed parachute.... did you do it right by following the instructions or did you just shove it in the bag and jump..... think before you leap!
