Hakuri 4

The Hakuri 4 is a multi-touch, slate-shaped smartphone designed and sold by Nashi Electronics of Shihaisha. It runs on the latest Nashi Operating System: PearOS 2.1 "Polar." It is taller and wider than its predecessor, Hakuri 3. The PearOS intelligent personal assistant uSay has been re-updated and vastly improved on the phone, and can now do more than its competitors such as Siri and S Voice.

Software and services
The Hakuri 4 uses the PearOS 2.1 "Polar" mobile operating system. Polar introduced a whole new design for the smartphones using the system, and added more interaction with the user interface of the system. uSay on the Hakuri 4 was greatly improved, which added many features that other intelligent personal assistants didn't have at the time. It uses Wolphram Alpha for all of its online searches.
