First came the scroll wheel, which is really cool. Now they’re marketing scroll wheels that can be tilted to the side (for scrolling left or right). I’ve tried out these new mice in the stores, and IMHO tilting the scroll wheel is kinda annoying. What they need to do is replace the scroll wheel with a small trackball. That way, you could scroll up & down, or left & right, or both at the same time!
What do you think? Good idea?
