Nokia (now Microsoft) has been making Windows phone in the Lumia line for a very long time now. HTC also has their own version on Windows Phone OS for a few years. Now Sony came up their own version of Windows 10 phone in their VIAO line.
The new VIAO Windows 10 phone, also known as VIAO Phone Biz is aimed at business users and supports the Windows 10 continuum desktop mode.

Most of the Lumia series comes in plastic casings that doesn’t feel premium, the VIAO Phone Biz however comes in a sleek silver finished aluminum build. So if you’re looking for a new Windows 10 based phone, this will look really sleek in your pocket.
The VIAO Phone Biz comes with a Snapdragon 617 chip and 3GB of RAM. Although the chipset is a medium range CPU, running Windows 10 on it is a snap. Windows OS has been known to run smoothly even on low specs. But should run much snappier on the VIAO Phone Biz.
The screen is 5.5″ 1080p with LCD display and the camera shoots up to 13-megapixel at the back and 5-megapixel front camera. Comes with 16GB of internal memory but can be added more via external SD card.

The VIAO Phone Biz will be released in Japan sometime in April and I do hope they will make it available in other parts of the world especially in Malaysia simply because my itchy hand would wanna play around with it. No news on the Malaysian price yet but tentatively it will be priced at USD$430.
If only Windows apps is as vast and widely available as Android and IOS, I will definitely use it.
