I purchased the BlackBerry 8100 Accessory Bundle because I update my appointments, contacts and receive emails on my smartphone from both my work and home computer, therefore I thought it would be a good idea to have a set of adaptors in both places, plus having a car charger is a no brainer. When I reviewed the individual items in this Accessory Bundle and seen the prices of some of the items I quickly realized that it was a much better deal to by the Bundle.
