In the beginning, there was one button. Then there were two. Then there were clickable scroll wheels and programmable toggles and solid-state slides. But nobody made a mouse as easy to use as your Mac. Until now. Mighty Mouse combines the capability of a multibutton mouse with Apple's signature top-shell design for the best of both form and function. Use it any way you work: Stick with single-button simplicity or click with multibutton efficiency. Time is round. Space is curved. Why should your mouse be linear? Plenty of applications require you to do more than scroll up and down. Mighty Mouse offers 360-degree scrolling capability, thanks to its Scroll Ball, perfectly positioned to roll smoothly under just one finger. Explore the farthest reaches of your files pan images in iPhoto, view timelines in iMovie HD and Final Cut Pro, traverse bars in GarageBand and Logic Pro with one hand tied behind your back (or holding a cup of coffee or typing). Mighty Mouse gives you room to roam. Less
