Logitech Rechargeable Trackpad for Mac
($54.52 at Amazon
If you're like me and dock your laptop to an external monitor while at home, partnering your machine to wireless peripherals is par for the course. Logitech now offers an alternative to Apple's Magic Trackpad for touch+gesture based navigation; the difference between the two is slight, but notable: Logitech's Trackpad is rechargeable, offers a slick glass surface, and the surface sits at a less angled incline, an improvement for anyone who found the 3/4" height of Apple's Trackpad too precipitous. All of OS X Mountain Lion's gesture's are supported and a mechanical click provides feedback just like your MacBook, making it a comfortable switch between on-the-go use and settling in at home.
