In fairness, expectations for Windows 8 are much higher than they are for Chrome OS. As consumers snap up tablets instead of replacing old laptops, Microsoft's touch-friendly operating system was supposed to revive the ailing PC market. Microsoft also piled on the marketing for Windows 8, with one report estimating $1.5 billion in spending, so PC makers were likely hoping those efforts would pay off.
Still, PC makers such as Acer need to shoulder some of the blame for weaker-than-expected sales. Windows 8 hybrids, which combine a tablet and laptop into a single device, were in short supply through the holiday season, and at this point it's tempting to wait for next-generation devices, such as hybrids based on Intel's Bay Trail and Haswell chips.
Meanwhile, it seems that Acer will keep making Chromebooks. That's good news if you want to see Google's browser-based operating system continue to evolve.
