I have the Torch. It's good but I wouldn't say amazing. What really annoys me is that the touch screen cannot be locked (or at least, I can't figure out how) when you are making a call, which means you have to hold the phone a bit away from your face or else risk calling people with your face while on the phone to someone else!
I like the browser that comes with the phone - it means you can use it both through the touchpad and the qwerty keypad, whereas Opera would not let you use the touch features on the screen with the browser (ie you had to use the trackball to navigate).
I wouldn't say I'm addicted by any means, but overall it is a good phone and I like the options of the touchscreen and the physical keyboard.
