ASUS was plenty busy at CES last week, but it held back at least one product on us — the B23E. This 12.5-inch business laptop packs a Core i5 or i7, up to 8GB of RAM and a maximum 750GB hard drive in a magnesium-aluminum alloy case. Other expected Pro-series niceties are also in tow, including a fingerprint reader, spill-proof keyboard and an anti-shock mounted hard disk. Looking at the spec sheet though, it’s not all gravy for this 3.4-pound PC. For one ASUS doesn’t state how long it will last on a charge, but we can’t imagine the three-cell 4,400mAh battery is going to impress with its longevity. We’re also sad to see resolution top out at a pedestrian 1366 x 768. For more details hit up the product page.
