Personally I'm really hoping to preorder online. I'm not a big fan of my local Verizon corporate store, they horribly screwed up on my wife's droidx upgrade.
In general they are rather clueless.
Are you considering that Costco deal though? I'm considering it very fervently...I think I may want to do it, mostly because I know Costco will have great customer service, and I just don't like Verizon's customer service very much. And the docks may come in handy, plus the extra battery is a necessity for an LTE device, even if this has great battery life.
But before that came out, I was SOOOO ready to pre-order lol.
