The other deals posted above are all integrated. Are there any comparable ultrabook type deals with integrated grfx? I haven't seen it. Also there are many reasons why the XPS line "stands out" from the crowd of laptops: first and foremost the build quality is superb to say the least.
Check the other laptops in the XPS line. MOST of them have dedicated graphics. I know the other laptops you guys are comparing this to have integrated graphics. I beg to differ. I still believe that dedicated graphics was the most attractive feature of the XPS laptops.
Take a look at the benchmarks between some of the dedicated graphics compared to the integrated ones. Some of the older xps laptops have a better dedicated graphics card than some of these with the integrated HD4000.
