Never had lag with the original OS .141 and definitely not with OS .246. I have had the 9700, 9000 and 8310 and the Torch by far is the most solid keyboard with none of the clackiness that my other berries had. I have more than two and a half dozen apps and have 377 MB free. The trackpad is better than the 9700 which was one reason I upgraded from the 9000. The touchscreen, trackpad and physcial keyboard make messaging, multi-tasking, and web browsing a much more enjoyable and productive experience. The battery life is on par with my 9700. The OS 6 version .246 has made it that much better. The menus are intuitive but will take some getting used to coming from the 9000 but they allow more control from a device management and customization perspective.
