Innovation Where You Least Expect It

This system is designed mainly for desktop applications, especially Excel, and web surfing. It's not easy to get used to, but once you're into it, handling it comes quite naturally. You don't miss the notches any more and find the gradual acceleration very enjoyable. The horizontal scrolling is very convenient, for Excel files more than anything because, in current resolutions, there are fewer and fewer web pages that don't fit into the screen.
