For me it was that the keys actually rattled if you ran your fingers over them, that would drive me crazy, with the backlight on the spacings where all over the place because they moved around so much and the typing experience was sub-optimal, if the XPS15 had had the keyboard on the 7560 I'd have bought it there and then. The 7560 was a nice looking/nice spec machine at 950 but the damn chassis bent just from opening and closing the lid in the first day. Dell can make good machines but mostly by luck I think sometimes. My current Laptop is an old Vostro 3750 I paid 500 quid for new (stacked discounts on the Dell site) and it has a better keyboard after 5 years of abuse. Damn thing just won't die.
