Dell must be doing something right, because according to recent sales figures, the PC maker has topped HP as the number one computer supplier in the States. The Texas-based computer-maker saw sales hit 5.35-million units in the fourth quarter of 2007 (a jump of 15.2-percent over the previous year), while HP came in second with a paltry and embarrassing 4.5-million units shipped. Interestingly, the third and fourth-place slots filled by Apple and Acer swapped hands, with Acer taking the lead due to its recent purchase of Gateway, resulting in a crazy 294.2-percent gain. The increase in numbers of the leader, however, seems to stem from Dell's shift out of direct sales to the sale of systems at retailers like Best Buy and Wal-Mart, though internationally HP still rules the roost, garnering a 19-percent market share worldwide. Of course, if they can overtake in America, Dell can certainly turn it around elsewhere. Watch your back, HP.

If you (or your kiddo) just happens to be a first through eighth grader in Birmingham, Alabama, you (or your offspring) will soon be playing with an XO during regularly scheduled class time. Mayor Larry Langford has recently announced that a $3 million deal was signed in order to bring in one laptop per child for the aforementioned grades, or 15,000 XOs in total. Apparently, the schools will become the first in the nation to receive heaps of the low-cost lappies, which were sold to the district at $200 a pop. As for logistics, students can expect to receive their machine on April 15, 2008, and while pupils will be allowed to take 'em home, the school system can and will disable any that inexplicably "disappear."

If you've yearned for an Asian-based GPS, but didn't feel like worrying over those annoying import duties or changing out the maps, Space Machine apparently feels your pain. Contrary to its title, this device actually doesn't include the marked highways on Jupiter and Mars, but it does manage to include NAVTEQ maps of North America in case you're traveling there, and also features a 3.5-inch QVGA touchscreen, integrated MP3 player, automatic re-routing, turn-by-turn voice guidance, SiRF Star III GPS receiver, 256MB SD card, car mounting kit, headphone jack, and a carrying case to boot. While most rebadgers actually take the time to slap their own logo on there, the GPS-306 apparently still rocks the Holux GPSsmile 51 motif, right down the "Holux" branding atop the screen. Nevertheless, we do appreciate the effort of importing the unit for us, and those attracted to the name more than its functionality can pick one up now for $399.95.

While it probably won't matter much once we're pitting one robot army against another, it appears that the US Air Force is looking into new "subterranean vehicles" that could be used to navigate to underground bombs, traps, or nuclear pods and defuse the situation from beneath. Although we figured the USAF would focus the majority of its attention somewhere above the Earth's surface, the newfangled moles would be deployed a safe distance from the target and "autonomously navigate itself to the target" while cleverly avoiding buried obstacles on its route. While larger digging machines can certainly accomplish the same task, the catch here is that the life-saving worm must not exceed "12 inches" in length and be able to run off of minimal battery power. Similar to other "teams" of robotic creatures feeding off one another to accomplish complex goals, the Air Force envisions swarms of these diggers penetrating and neutralizing potential hotbeds for underground explosives, all without sacrificing human lives. Now if we only had one of these bad boys to sneak up into Best Buy's PS3 holding closet last night, we'd have a winner.
