Fujitsu actually has a working Windows 7 Smartphone, the Loox F-07C, which not only comes with Microsoft's desktop operating system but also runs on Nokia's Symbian OS.
The device's configuration reminds us of a tablet except that it is at least a third of the size and weight of the lightest Windows 7 tablet we've come across, AND comes with a proper keyboard with a trackball, a slide out one not unlike those found on the HTC Desire Z.
The F-07c runs on a 1.2GHz Intel Atom Moorestown CPU, has 1GB RAM, 32GB eMMC Flash, comes with a 4-inch 1024x600 pixel display, a five-megapixel rear camera and a VGA front facing one, Wi-Fi, Bluetooth and has a nifty little cradle that has USB, HDMI and Ethernet capabilities.
Akihabaranews (opens in new tab), which had a hands-on session with the device, found it to be pretty usable and running Windows 7 "damn well".
Although it weighs a rather hefty 218g and is 19.8mm thick, roughly twice the weight of the Samsung Galaxy S2 and twice the thickness of the LG Optimus black, the fact that it can run Windows 7 comfortably gives it an undeniable selling point.
Akihabaranews did not report on either the battery life or the functionality of the Symbian OS - which arguably is the mobile phone's platform, which is a surprising choice given that they might as well have used Windows Phone 7.
