Ask HN: Microsoft's reply to Chromebook

Is there a chance that Microsoft will come up with a Chromebook competitor or is already working on? And it makes sense also at least in US and other developed countries where fast internet facilities are always available. Also they have got everything they need: Bing, One Drive, Office 365, Browser Spartan and Windows Store. It will be best for all those people who mostly work on the internet and removing all the legacy code of Windows would definitely make it much more secure and fast or may be they can build on top of linux kernel. Above all, it will be cool to have one!! Any thoughts?
