We heard that Dell's Inspiron 15 would go on sale later this month, and apparently that means now. Dell's latest 15.6-incher is up for order as we speak, and as expected, $699 gets you in the door. Those with extra cash to burn can upgrade to 4GB of RAM, a Blu-ray drive, 320GB of hard drive space and a 9-cell battery. So, you in or what?[Thanks to everyone who sent this in]Filed under: Laptops
