I am on the verge of buying a 'Dell Studio XPS 15 L502X' laptop from a company called 'ecomputers' on ebay (seller...thechef01). It is a good machine with the following specs..Core i7 2630QM, 6Gb ram, Nvidia GE force GT 560M 2 Gb,500 Gb Hd and is very cheap at £799. My problem is that as far is I know Dell never made a 'Studio XPS 15'. They did make 'Studio XPS' hybrid models but not a '15'. I'm baffled. Any ideas?
