Japan's NTT DoCoMo plans to launch what it calls the world's smallest Windows 7 computer in the next two months.
The device can fit in a jacket pocket and contains an Intel Atom processor and a 4-inch touchscreen with 1,024 pixel by 600 pixel resolution. The phone is being developed by Fujitsu and is scheduled to go on sale in Japan sometime in June or July this year.
The device will use a Moorestown processor, but other detailed technical information about the device wasn't announced on Monday.
However, it appears very close to the mobile Internet device idea that Intel has been pushing with little success for the last few years. Mobile Internet devices are intended to bridge the gap between smartphones and tablet PCs by offering a PC-like performance and operating system in a smartphone form factor.
The new device will blur the line between PC and smartphone thanks to the inclusion of many features commonly found on cell phones in Japan, such as GPS (Global Positioning System) navigation, HSPA (High-Speed Packet Access) 3G data, an e-wallet, local navigation and guide services, video calling and support for earthquake early warning messages.
"It's aimed at heavy data users," said Naoko Minobe, an NTT DoCoMo spokeswoman.
The phone will run for up to 600 hours in standby and provide up to 370 minutes of 3G talk time, according to NTT DoCoMo estimates.
It measures 12.5 centimeters by 6.1cm by 2cm and weighs 218 grams.
That makes it much thicker and heavier than a range of Android smartphones due on sale in the coming months that NTT DoCoMo also previewed on Monday. The seven new Android phones and the Windows 7 device have a comparable length and width, but the Windows 7 phone is about twice as thick. The lightest of the Android phones weighs 110 grams and the heaviest weighs 140 grams.
None of the carrier's new line-up of handsets runs Windows Phone 7, Microsoft's new operating system for cell phones. NTT DoCoMo said it continues to evaluate the platform but has no current plans for a phone based on the software.
