The Ativ name may be silly, but Samsung Electronics is betting heavily on it as the namesake for anything related to Windows. In a showcase Thursday that featured a slew of products, Samsung’s Ativ line played a central role. Ativ has become the umbrella brand that includes laptops, tablets, all-in-ones, and smartphones, and some of the devices were on display. Samsung is hoping history repeats itself with Ativ. It previously poured its resources into developing the Galaxy brand for anything associated with Android, and its flagship Galaxy S line of smartphones is a smash hit, with the Galaxy name extending into multiple lines of successful phones and tablets. Microsoft could certainly use the jolt. The reception for Windows 8 has been tepid, with users uncomfortable with the new tile-based user interface. In May, Microsoft boasted of 100 million Windows 8 licenses sold, but critics contend usage and interest remains low.
