You know, we see a lot of ultraportable laptops these days, it's not like it's virgin territory for us, but we'd say the last time we were this blown away by a form factor was the VAIO X, or maybe the Adamo XPS in all its weird-hinge glory. LG's X300 is simply thin. Cramming 11.6-inches of screen and premium netbook parts (2GHz Atom Z550, HDMI out, up to 2GB of RAM and 128GB SSD, even some 3G and Bluetooth for good measure) into a 0.68-inch thick form factor is impressive, but we're even more struck by how insanely light this thing is -- it feels more like holding an e-book reader in hand than a laptop. The plastic build feels very solid, and the textured pattern on the back falls into the realm of "premium," not "gaudy." The keyboard isn't the best action-wise, but there's zero flex because there's nowhere to go. Our biggest concern is the trackpad: it's nice and big, but there's a "virtual" click mechanism where you tap to click the button portion and get a haptic response -- it might be the evolution of the "click pad" concept, or it might be a pain in the ass. Even the screen was bright and quality, though too glossy for our taste. We're told the laptop is headed to the US, but we're not sure when -- hopefully soon, since it's starting to ship internationally this month. Check out a video walkthrough after the break.
