Yea, I know I am a bad boy. I use a Blackberry rather than a SmartPhone. SmartPhone is real intriguing but the Blackberry works for me. The big reason I got the Blackberry was to synchonize my address book with Outlook. It is hard to call someone when the updated phone number is not on your phone but is still back in your office. A PDA is a solution but I prefer the phone format. The secondary reason was to read my Yahoo email in my spare time. A month ago I decided to setup my Blackberry to download my business email, too. Blackberry works fine with OWA. An updated calendar and task list is nice but not critical I have occasionally used the web browser and Opera Mini but they are painfully slow.
Although my phone is only two years old I have started looking at replacements. The biggest feature I am interested in is faster web access via T-Mobile and a phone modem capability for my laptop. The new phones are nice but I can wait.
