A: The dual-boot button for Windows 7/Symbian. B: QWERTY keyboard with trackball. C: The ultimate test of patience.

Japanese carrier NTT DoCoMo today announced 24 handsets for its summer lineup, and one of the most interesting has two operating systems: one mobile OS, and one OS you wouldn't expect to find on a cell phone.

The Fujitsu LOOX F-07C, one of the most peculiar hybrid smartphones in recent memory, can use the Symbian OS or Windows 7 Home Premium (32-bit). The QWERTY slider features an 1.2GHz Intel Atom (Moorestown) processor, 1GB of RAM, and 32GB of built-in storage space. A trackball and left click button are also located near the keyboard. My notebook, which was already feeling a bit irrelevant due to tablets, is shaking in its sleeve.

The 70,000 yen ($865) F-07C has a 4-inch touch-screen capable of displaying an impressive 1,024x600 resolution in Windows mode (Engadget believes the device runs at 297ppi, putting it just a shade below the iPhone 4). According to Fujitsu's Web site, the camera button can slide up and down to zoom in in Windows, which could be more handy than pinching and zooming when you're in a rush. A dock and widgets in the miniature version of Windows 7 allow you to access your favorite applications easily. A full version of Microsoft Office 2010 with a two-year license is also included.

Battery life while running Windows 7 on the device clocks in at only two hours, which will mean you'll definitely be in a rush when trying to do something using that OS. Fortunately, normal cell phone battery life estimates are much better at 600 hours standby and 370 minutes of 3G talk time.

The camera within contains a 5.1-megapixel sensor with face, scene, and smile recognition. Connectivity includes Wi-Fi 802.11b/g/n, GPS, HSPA/3G, e-wallet, video calling, and other special services only found in Japan (such as earthquake notification).

Does it run Microsoft Bob

The real selling point of the F-07C could be the cradle accessory (sold separately) that features HDMI and USB 2.0 ports. Fujitsu notes that you can connect a peripheral (such as a printer, keyboard, or mouse) to the dock and use it within Windows mode, while the HDMI output can turn your TV into a PC. Not bad for a smartphone, and somewhat reminiscent of the Android-equipped Motorola Atrix.

Fujitsu has labeled the navy blue F-07C as the "world's smallest Windows 7 PC." What about the "world's most frustrating to use Windows 7 PC"
