So, to my knowlegde, only 1 production laptop uses DDR3 RAM, and that is the Lenovo T400. I don't think Dell costumers know the difference, so they are in no hurry. The improvements in performance are decent, but where it really helps is in battery life. So with DDR3 RAM, LED backlit, and hybrid-graphics (the discrete graphics card turns off and let's the integrated graphics do the easy work), battery life goes through the roof. where is apple on this? cmon, lenovo of all companies has this (i don't think they have the hybrid graphics...). cost isn't that big of an issue, the lenovo 14" laptop with LED, discrete graphics, and 4 GB DDR3 ram is only ~$1500. Maybe they are waiting for intel's new non-FSB chips to make the jump. Anyone have any thoughts or know of other laptops with DDR3? thanks.
