Just a week after Microsoft announced the first major update to their Windows Phone operating system, an Acer branded Windows Mango device was released at Computex.

The device is powered by Qualcomm MSM8255 Snapdragon processor at 1 GHz and boasts of a 3.5-inch WVGA capacitive screen with 480 x 800 resolution and a 5 megapixel camera with autofocus. Connectivity options include WiFi, Bluetooth 2.1 and quadband GSM support.

According to reports, the handset will come with 8 GB of internal storage. Recently, Microsoft Corp launched an update of its Windows phone software, hoping a host of new features will help it close the gap on smartphone leaders Google Inc and Apple Inc.

More interestingly, the Acer W4 continues to use a single core processor while Android competition is moving towards dual-core processors. The device is also missing a NFC (Near Field Communication) chip, which is quite interesting as Android devices like the Nexus S and the Galaxy S II are quickly adopting NFC.

Microsoft said the update involved 500 new features, including Internet Explorer 9 as the mobile browser, Twitter and LinkedIn feeds integrated into contact cards, automated Facebook check-ins, and access to more than 17,000 downloadable applications.
