I have several friends that have bought this device - they are extremely technical and love to tinker endlessly with their gadgets.I give this phone a lower rating because I need a very reliable phone that allows one hand operation for all functions. I want the phone to have a full keyboard and work well with email, calendar, and contacts. My preference is to pull the phone out of the box and have everything working immediately. I bought the 8125 and returned it a week later for the Blackberry 8700 (very satisfied with the decision by the way). The Blackberry 8700 also fits in my pocket better.The 8125 is a computer with all the positives and negatives that go along. If you don't mind using two hands to operate the phone, a quirky touch screen, and hours tweaking the PDA then this may be the phone for you.I know someone else that bought the 8125 as a PDA only and uses a RAZR as his cell phone. Since I wanted one device that was a good phone and PDA, I went with the Blackberry. The Cingular customer service rep said that people switching from earlier versions of the Blackbeery to the 8125 tend to return the SmartPhone a lot.You will like this phone if you:* Don't mind spending hours to "tweak" the phone* Don't mind using two hands and a stylus* Don't mind having to slide out keyboard for email* Want excellent Outlook compatibility* Need to edit/view Word and Excel documents* Use a bluetooth headset for your phone* Don't mind a little heavier and thicker phone
