Query: Last Straw

My complaints about the D-Link 650+/614+ products mirror most of the negative reviews:- Blue screens- System freezes- unstable performance- card goes dead and laptop needs reset- less than advertised speed- causes progressively slow laptop response- tech support was uselessSo I don't understand how others have had such great experiences.I even recognize the same shining reviews on other sites. Looks suspicious, does D-Link have a positive campaign to offset the negative reviews?I've had similar experiences with other PC/Laptops and third-party products so I give up. I am going back to the Mac. Good bye and good luck PC world!
