Apple Sues To Stop Power Adapter Knock Offs
Apple is suing a company that makes knock off power adapters because they certainly can't have a power adapter besides their own setting your MacBook Pro on fire. 
Apple's complaint charges that Media Solutions Holdings, through the Web sites www.laptopsforless.com, www.laptopacadapter.com and www.ereplacements.com, sells "various consumer electronic accessories at retail, including knock-off power adapters for use with genuine Apple portable computers."
