This was my second Sony-Ericsson phone (the first was a T68i), and the fatal flaw in both phones was poor joystick design. In both cases, after about a year and a half of light to normal use, the joystick started to work erratically. Movement either did not register, or registered as 'Enter' rather than movement. Since you cannot do anything on this phone without using the joystick, it becomes difficult to perform basic actions, such as locating and calling a contact. It also means that I frequently make and have to quickly cancel multiple accidental calls due to unintended input before I make it to the intended number in the contact list. I will never again purchase a cell phone that has a joystick.Other than this one (very major) problem, this phone has served me well. Bluetooth synchronization is handled flawlessly by iSync on my Mac (at least for contact information; I never tried the calendar), and I was also able to used the phone as a modem, connecting my Powerbook to the internet wherever I had cell service. The form factor is just about perfect; the phone is unobtrusive in a pocket, and it is easy to hold. The side volume buttons are a great touch. I give it three stars because it was exactly what I wanted and worked well until the joystick started malfunctioning.
