Samsung has released a new range of tough-build business notebooks in its Series 4 and 6 line-ups ahead of next month’s new range of Series 3 consumer units.While the upcoming Series 3 laptops give buyers a choice of Intel or AMD components, the new Series 4 and Series 6 notebooks each come stocked with an Intel i5 processor.

The hot commodity on these business-centric computers is high durability on the back of anti-shock and pressure resistant casings, a spill-resistant keyboard as well as 180 degree-flexing metal hinges.

The $1,199 Series 4 NP400B5B-S01AU model offers 4GB of DDR3 RAM, a swappable 500GB hard drive running at 7200rpm and a switchable nVidia NVS 4200M (Optimus) graphics card and Intel HD Graphics.

The 15.6 incher also features a range of up-to-date connectivity options including Bluetooth 3.0 and two USB 3.0 ports next to its two conventional USB 2.0 ports. There’s also the full range of memory card readers and HDMI and VGA connections.

As a business notebook, it comes with a range of security functions and features like hard drive passwording, Kensington lock ports, a free fall sensor and fingerprint reader as well as its Duracase Pro chassis for durability.

It rolls in at a hefty 2.5kg with its 6 cell battery.

The $1,399 Series 6 NP600B5B-S01AU sports most of the same specs as the Series 4, but features a larger hard drive (also swappable) than the Series 4, though running at a slower 5400 rpm.

A step up from the Series 4, this notebook sports a Duracase Pro MG body that is reinforced with a magnesium alloy for heftier resistance against drops.

It comes in slightly heavier than the Series 4, but with a higher battery life.
