3K is targeting the machine as a low-cost portable internet appliance for professionals and students, offering web browsing, Flash games and instant messaging.
With a boot-up time of under eight seconds, the RazorBook 400 is designed to be turned on and off instantly with an energy-saving processor, no fan and quiet running.
The Linux-based operating system is supported by a shock-resistant 4GB solid-state drive.
The open source Office Suite opens most Microsoft files and includes an email client and a PDF reader as well as the Mozilla Firefox browser.
"There has been a lot of comparison from bloggers to the Asus Eee PC due to its similar 7in LCD form factor," said 3K chief executive Dan Jacobs.
"The 3K RazorBook 400 is a unique product that was designed as a low-cost portable internet appliance, not to replace your home PC or notebook computer."
