Samsung has introduced three new notebook lines for professionals. Series 2, 4 and 6 laptops have extra features to ensure durability such as metal hinges, pressure-resistant casings, spill-resistant keyboards, anti-shock hard drives, and the systems are accompanied by a lengthy three-year warranty with US-based tier 2 customer support. Series 4 and 6 have added perks such as fingerprint readers and a trust module, while only the Series 6 has a magnesium alloy shell that further improves ruggedness.

Series 2 kicks things off with 12.5 (Celeron-based) and 14-inch (Core i3-based) variants, featuring Intel integrated graphics, up to 4GB of RAM, and 320GB of storage. Series 4 is offered in the same form factors, except both can be equipped with Core i3 or i7 chips as well as up to 6GB of RAM and a 500GB hard drive. Meanwhile, Series 6 comes in 14 and 15.6-inch models with a Core i3 or i7, up to 8GB of RAM, a 500GB HDD or 256GB SSD, and an optional Nvidia NVS 4200M discrete graphics chip.

Series 2 and 4 notebooks are limited to a 1366x768 display, while the 15.6-inch Series 6 gets a 1600x900 resolution. The higher models feature a docking station connector and are quoted at seven hours of runtime on a six-cell battery -- neither spec is listed for the Series 2. All systems come with USB 3.0 connectivity, a 1.3MP webcam, as well as Samsung's Easy Migration service and Windows 7 Professional. Samsung didn't share pricing but Series 2 and 4 are coming in April while Series 6 should follow in May.
