Chrome OS on a desktop is being developed by Acer, with the company experimenting with a new all-in-one PC running the Google operating system.

Yesterday Acer announced its upcoming Chromebase device, just after Google and its partners unveiled a range of new Chrome-related products slated to launch soon.

Acer's Chromebase is set to arrive in the second quarter in North America and Asia Pacific. The all-in-one has a 21.5-inch 1080p touchscreen display and an Nvidia Tegra K1 quad-core processor.

Included are a webcam, two speakers, and HDMI and USB ports, in addition to Bluetooth 4.0 connectivity. No price was immediately given.

Last year, LG launched its own all-in-one Chrome OS device for $349. Vendors have also come out with so-called "Chromeboxes", which are basically mini desktops that run the OS.

So far, however, the desktop models haven't had much appeal, said Tracy Tsai, an analyst with research firm Gartner. Instead, most of the demand has centered on notebooks running Chrome, also known as Chromebooks.

The Google operating system is still a niche player in the market. Last year, about 85% of all Chrome devices were sold in North America, and mainly to schools, according to Gartner. Globally, the OS only had a 4% share of the mobile PC segment.

That probably won't charge in the near future, given that customers still favour Windows, and Chrome OS only supports a limited number of applications, Tsai said. But even in the desktop space, vendors will still try to experiment with Chrome OS.

"The vendors always want to find any possibility to grow the market segment, and perhaps the all-in-one will find a place in schools," she added. "Students may want a bigger screen to work with."

Google seems to also have that in mind. The company has worked with Asus to come out with Chromebit, a thumb drive with a computer inside that can run the OS, which can be plugged into a TV or monitor.
