I have no problems with my new XPS and do not wish to post my service tag number.   
I have to say am impressed.  My VP has been needing a new laptop for a while now so I gave him my Thinkpad Xeon laptop workstation!  It was no slouch on performance but the 9510 XPS with l9, 32gb and TB disk blows it away!!  We both do AutoCAD and the discrete graphics is greatly enhanced on the XPS. Not to mention the build quality in the XPS.  I am sold on the XPS and can’t wait to do my customer’s favorite, 3D rendering   Also a question.  How much power does the instant on when lid is opened consume.  I really like it and it is a great feature for the customer. Mew to the forum, hope you people do not Lind me hanging here for a while!
