The latest Windows Phone rumour points to a new one from PC vendor Vaio

A second third-party Windows phone? What madness is this?

Sony spinoff, Vaio Corporation, is expected to launch a phone based on Windows 10 Mobile this week, following Acer into the suddenly hot market for third-party Windows phone hardware. reports that Vaio will be holding a press conference to announce the new phone on February 4. Executives from both Microsoft and Vaio are expected to attend, including Takuya Hirano, the president of Microsoft Japan.

Vaio representatives did not respond to requests for comment by press time, although published a photo which named both Acer and Vaio - as well as Mouse Computer, freetel, ThirdWave, and NuAns - as Windows 10 Mobile partners dating back to last October.

Vaio is a spinoff from Sony, which manufactured the Vaio PC brand in the late 1990s until March 2014, when Sony sold off the division to Japan Industrial Partners. JIP then resuscitated the business under the Vaio name. Sony went on to sell numerous smartphones based on the Android OS but never became a major player.

Launching into a void

Microsoft has already launched the Lumia 950 and Lumia 950XL as its own flagship smartphones running Windows 10 Mobile. Despite these new models, the company has suffered a sharp decline in Lumia sales. Into the breach has stepped companies like Acer, which launched the Liquid Jade Primo Windows 10 Mobile phone last year and then showed it off at CES.

Why this matters: If Microsoft can’t sell its own Lumia phone, it's hard to say whether third-party companies like Acer and Vaio will be able to pick up the slack. Still, Sony was said to be interested in manufacturing a Windows Phone as far back as 2013, when it would probably have been built around the Windows Phone 8 operating system. It’s likely that some of the same attitudes transitioned to Vaio as part of the spinoff, to avoid the same Apple-Google hegemony that defines the smartphone market today.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
