iSkin today announced an updated ProTouch PB keyboard protector for Apple’s new iBooks and PowerBooks. The form-fitting ProTouch PB is made of a flexible, high-grade silicone that provides a transparent barrier against spills, dirt, and other unwanted elements that may get in between the keys of the keyboard and potentially cause damage to the laptop. The ProTouch PB (US$19.99) will begin shipping Dec. 11, and will be released initially in Arctic (frosted transparent). Sonic (transparent electric blue) will be released shortly afterwards. iSkin today also launched its iSkin Tattoo Service, which enables organizations, businesses and institutions to order iSkin products emblazoned with their logo, Web site address or company message.
