I apologize if this has been discussed ad-nauseum in other posts, but I just can't find the precise information I'm looking for... (The search algorithm on this forum returns WAY too many results to be useful.) Now on to the actual questions... The Seidio 1500 mAh "slim" extended battery only offers an additional 200 mAh of capacity over the original Motorola battery. (By comparison, the big Seidio battery offers over double the original battery's capacity). Has anyone purchased the 1500 mAh battery? Did you actually notice a difference between it and the original battery? Next question: The larger 2800 mAh Seidio battery offers LOTS more capacity, but it would appear that it will not allow you to fit the phone into the original Motorola Multimedia Dock. Can anyone verify this? If I were to purchase the large battery, would I also be required to purchase the Seidio Desktop Dock in order to have the same functionality I've got with my current regular-battery & Multimedia Dock? Thanks for your time.
