Input: Moving from a Windows laptop to a Macbook was like going from a rat-infested cave to a shiny NASA control center. However, the one thing I missed from my old Windows PC was the trackball. So I got a new one for my Mac. You can download the Logitech Control Center for Yosemite & use the 2 little buttons for scrolling up/down pages. It works great for creating drawings in iDraw or doing page layouts in Pages. This gadget is a near-perfect design that's been around for years. (Putting 303 Protectant on the ball makes it slicker than hawg snot.)<br />Just wish they made a &#34;pure Mac&#34; version with a touch area for up/down/zoom right above or below the left/right switches & a left/right touch area right in back of the ball. That would be trackball Nirvana.
