Hi, I was wondering if anyone has used any cases like the snap on VZW ones, the silicone or leather wrap around ones shown in the launch packet. I'm realizing that there's a good chance that they won't be able to make a "skin" for the back so I'm thinking of getting a screen protector and one of these style cases. However, I also want to get the dock so I'm wondering how long these take to get off and on. I'm sure that the skin will still allow me to dock with it still on, I just don't want to have to do a lot of wrangling to get the back case on each day. So, what do you think? Never used a case like this and could use some input. Thanks in advance!
