“We are committed to evolving this technology,” said Acer chief executive J.T. Wang.
“By the second quarter of this year we will have four models of ultrabook and more to come.”
Acer is ranked among the world’s top five branded PC vendors.
The Taiwan-based computer titan will begin shipping Acer Aspire 5 models in the second quarter of this year, with prices to be disclosed in coming weeks.
“That S5 is quite significant,” analyst Tim Bajarin of Creative Strategies said after the Acer press event.
“It looks like the thinnest and lightest, and it sets the bar for the rest of the ultrabook vendors,” he continued.
Ultrabooks will be stuffed with Windows 8 therefore, they are not having battle with Apple and hopefully, it will make make up at least 35 per cent of the Acer product line by the end of this year.
“We believe Microsoft will take care of Windows devices; Google will take care of Android devices, and Acer will take care of in between,” Wang said.
“We will make Windows work very well with Android and other platforms too.”Bajarin described Aspire S5 as the first viable Windows equivalent of popular MacBook Air laptops built by California-based Apple.
