Treo fans looking to switch over to a new streamlined BlackBerry device may want to wait for future releases. This is the best BlackBerry to date in most capacities, but it still lacks the robust expandability of its competitors. With limited third vendor application support and Bluetooth capabilities the 7100 series gets knocked out after a few strong rounds as a challenger to the Treo 650. If you are solely looking for the best pound for pound device for email and phone calls only, the 7100t has been designed to fit in your pocket. The messaging capabilities, newly designed keyboard interface (SureType predictive text), push email service and speakerphone are top notch on this device. However, the lack of multimedia packages, limited Bluetooth usage and slow evolving browser capabilities leaves me yearning for more out of Research in Motion.
