Samsung rolls out an updated version of their popular NB30 netbook, that includes more powerful components and a few cosmetic changes over its predecessor. The new boy, known as the NB Pro, boasts that same Atom N450 processor inside, paired with a basic 10.1-inch 1024×600 display, up to 2GB of RAM, a 160GB hard drive, three USB 2.0 ports, WiFi, Intel GMA 3150 for the graphics, Windows 7 Professional Edition and a battery pack, claimed to deliver up to 6.5 hours of continuous work. It will run for $519 (expensive!) once available, somewhere towards the end of next month.
