Many typical 'consumer'- type of applications, such as word processors, email apps and web browsers require up and down scrolling, hence the wheel mouse.
But I seem to work with a lot of apps in which I need to scroll sideways, too.
Anyone heard of a mouse that had a two-axis sphere instead of the wheel? Alternatively, do you think it would be usable via a software hack which scrolls sideways when the wheel is being pressed while scrolling?
Just a thought.
