Whoa, boy -- HP just went loony on us tonight, and in the midst of everything else, we found a new pair of HDX notebooks. Kicking things off is the X16, which boasts a woefully under-pixelated 16-inch 1,366 x 768 resolution display, a 2.26GHz Core 2 Duo P8400 CPU, NVIDIA's 512MB GeForce 9600 GT, 4GB of DDR2 RAM, a 320GB 5,400RPM hard drive, dual-layer SuperMulti optical drive and built-in WiFi / Bluetooth. As for the beastly X18, you'll find a lot of the same kit internally, but the 18-inch 1,920 x 1,080 display is one we can really salivate over; additionally, this one ups the ante with twin 250GB HDDs and a Blu-ray reader. Each unit includes the essentials: an Ethernet port, multicard reader, integrated Altec Lansing speakers, ExpressCard slot, four USB 2.0 sockets, audio in / out, HDMI / VGA and a 4-pin FireWire connector. Both units should ship later this month starting at $1,249 and $1549, respectively.
