Many people seem to be worried about what Chrome OS can't do. However, I am more concerned with what it can do. And there's another skill to add to the operating system's list: media playback. In a recent interview with Ars Technica, the directing engineer for the Chrome OS project explains that Chrome OS, without any web app in play, will be able to play your music and videos.
"...You might just have a USB key that has a bunch of MP3s on it, so you want to be able to plug that in and listen to those MP3s. There might not be any controlling webpage for that activity, but it’s clearly something you need to be able to do in any reasonable operating system or browser. So we’re doing a lot of work to make Chrome and Chrome OS handle those use cases really well"That said, Mathew Papakipos just might have put many fears to bed. While numerous people have said that a "browser" can't do everything they need to do, this shows that Chrome OS will be able to do quite a bit.
