Taiwan's PC makers Acer and Asus are unveiling a new generation of ultra-thin laptops at the world's second-biggest computer show this week.

On Monday, both Acer and Asus unveiled a new generation of laptop-tablet hybrid known as the Ultrabook.

At an Acer pre-Computex presentation Monday, group president Jim Wang said the computer vendor has "reinvented" itself over the past two years, engaging in "progressive design" that aims to not only satisfy users' needs but also allow them to enjoy the devices.

Wang unveiled the 8-inch Windows-8 based Iconia W3 tablet that combines both home and office functions. Powered by Intel's Atom chip and Windows 8 OS, the tablet will be marketed later in June.
