This product proved to WASTE more time than provide a friendly time-saving fix. I realized that the device synchronized some of my appointments, but not all-day events like birthdates and anniversaries. I also realized that none of my Outlook address book contacts were synchronized. This device is a waste of money, for any customer. I received this item as a christmas gift. After realizing that a PDA was a great idea, I chose to purchase a HP iPAQ h1935 Pocket PC. It sells for 200.00 and is worth every penny. If you are a mobile phone user, I would recommend purchasing a Samsung i700 which combines a Pocket PC with digital camera and cellphone.
