It’s no secret that people like Chromebooks. That can’t be good news for Microsoft, which used to own the market for cheap computers. Not one to take this sort of encroachment lying down, Microsoft came out with a lower-cost version of Windows 8.1 that PC makers could use to build small, lightweight devices inexpensive enough to take on Chromebooks. The HP Stream 11 is among the first of these so-called Chromebook killers: an 11.6-inch laptop running full Windows and priced at just $200. For the money, it looks and performs like a netbook, with a colorful plastic shell and an Intel Celeron processor chugging away under the hood. Then again, though, you also have the option of installing traditional desktop apps, which you can’t do on a Chromebook, and Microsoft is further sweetening the deal by throwing in a terabyte of OneDrive storage and a yearlong subscription to Office 365. So is this just netbooks, redux? Or does an aggressive price make all the difference?
