It is NOT VZW reps' fault that some of them know nothing about something that has not been out yet. Obviously they have not been informed about the Thunderbolt. Some get their info from the internet just like you and me. They have been trained to sell the products they have in store .. and have been trained for. Obviously they have not been trained about Thunderbolt. I don't blame them. To be honest, how many of us know every single detail about our own jobs? All of us are not aware of something or other about our jobs. Let's not be too harsh on them.
Yes, if they are rude to the customers and behave in not so courteous manner, then they can be held at fault. But I would not talk trash about them just for not being able to answer the questions about a device which only a handful of people out there have a detailed knowledge of.
But hey I am not judging you. This is just my point of view. If you are still going to flame, be my guest
