according to this.. the FHD model is the one that comes with windows home PREMIUM and is priced at 33xx and the WLED HD comes with windows home BASIC and is priced at 28xx.

but as per your page.. you are selling at 2840 with windows home BASIC.. but you have FULL HD. I just wanted to clarify if there is some mistake with that or not. sorry for the inconvenience..
