Acer Inc. is expected to announce quarterly results sometime today, according to Yahoo Finance. If the PC maker’s latest quarterly earnings do surface, they could provide new clues about Windows 8 tablet and ultrabook sales as well as Google Chromebook sales. Acer President Jim Wong in January suggested that Chromebook sales were heating up but Windows 8 wasn’t doing much to give Acer a lift. Has that trend continued? Hmmm???
