The 1720 and 1721 appear to be just what we heard: Santa Rosa-based Intel and AMD machines, respectively. The 1720 maxes out with a 2.2GHz Core 2 Duo T7500, a 17-inch WUXGA TrueLife display, 256MB of GeForce 8600M WP graphics, up to 2x 2.5-inch SATA disk with RAID 0/1 support (!), 802.11n and Gigabit Ethernet, a whole mess of inputs and output and USB-only docking station. The 1520 packs much the same only with a 15.4-inch WSXGA+ TrueLife display and what appears to be a hybrid hard drive option and Blu-ray disc drive which is likely available for the 17-inch as well. the 5.5-pound 1420 offers a 9-cell Lithium Ion battery option and the same HHD option only under a smaller 14.4-inch WXGA+ TrueLife display. Hey, that's what the forum peeps are saying.
