Asus K50IJ 15.6" Laptop, Core 2 Duo 2.2GHz / 4GB / 500GB for $549.99 shipped after a $100 rebate.  Here is a screenshot for your reference.  It features an Intel Core 2 Duo CPU at 2.2GHz, 15.6" LCD with LED backlight at 1366 x 768 resolution, 4GB RAM, 500GB hard drive, DVD burner, wireless 802.11b/g/n, 1.3MP webcam, Windows 7 Home Premium 64-bit, and more.  Asus also provides a rather unusual One Year Accidental Damage Warranty, which protects against drops, spills, power surges, and fire damage.
