For a number of quite sound marketing reasons Windows-powered mobile phones rarely come near to the hardware in current Android powerhouses, but with the introduction of Windows 10 and sophisticated features like Continuum, this is set to quickly change. Higher-end offers, like the Acer Jade Primo are starting to appear and it naturally, it was a matter of time before China OEM's enter the market as well. The latest such offer comes courtesy of Elephone. Its "Vowney" model was first spotted a few months ago and if rumors are true, it does promise to dual-boot Android and Windows 10 on quite a capable hardware platform. This includes a 5.5-inch, QHD display (2560 x 1440 pixels). 3GB of RAM and an octa-core Mediatek MT6795 SoC. Other details include a 21MP camera (probably an Exmor RS IMX230 sensor), a large 4200 mAh battery and even a fingerprint sensor on the back. The phone can be preordered today, starting at $299, which is definitely not a bad price for a capable Windows 10 device. It is also worth noting that unlike Android, which has free access to AOSP, Microsoft charges OEM for its OS, so, presumably, there is a charge for the software calculated in there as well. According to the website, the first units should start shipping on September 30, so if you get on board, the wait isn't all that...
