Acer W4 vs Sony Ericsson Xperia Arc S

The maturation of the Windows Phone 7 product continues with the introduction of Mango in the Acer W4. Meanwhile, the competition from Android handsets further heats up with the addition of the Xperia Arc S to Sony Ericcson’s new lineup. The following comparison reveals how these two new products stack up against each other.

Dimensions and Form

  • Acer W4 – Unreleased
  • Sony Ericsson Xperia Arc S – 125 x 63 x 8.7 mm, 117g

Acer has yet to release official dimensions and weight, but hands-on feedback has indicated the device will be made of the same build and lightweight plastics as other Windows Phone 7 products. Generally, the Sony Ericsson Xperia line promises a quality chassis, although at this point it is difficult to speculate on either.

Winner: Draw

Display Screen

  • Acer W4 – 3.6 inch WVGA touchscreen, 480 x 800 resolution
  • Sony Ericsson Xperia Arc S – 4.2 inch LED-backlit LCD screen, 480 x 854 resolution

In terms of pixels per inch, the Acer W4 packs more density into its smaller screen with 259ppi versus the 233ppi in the Xperia Arc S. On the other hand, the 3.6 inch screen may be two miniscule for some functions.

Winner: Draw

Processing Power

  • Acer W4 – 1GHz Qualcomm CPU and 512MB RAM
  • Sony Ericsson Xperia Arc S – 1.4GHz Scorpion CPU, Adreno 205 GPU and 512MB RAM

From memory to pure clock speed, the Xperia Arc S trounces the Acer W4 in processing power. The minimalist Acer W4 is currently sufficient for most tasks, but there is speculation over whether its hardware will hold up in the future.

  • Acer W4 – 5-megapixel primary camera
  • Sony Ericsson Xperia Arc S – 8-megapixel primary camera

The Acer W4 is outfitted with an unassuming, 5 megapixel camera with auto-focus and LED flash. In contrast, the Xperia Arc S boasts an 8 megapixel primary camera with the same features plus smile detection, geo tagging and 3D sweep panorama, as well as a secondary camera for video calling.

Operating System

  • Acer W4 – Windows Phone 7 Mango
  • Sony Ericsson Xperia Arc S – Android 2.3.4 Gingerbread

The Android Gingerbread software is an established, well-rounded interface, embedded under Sony Ericcson’s TimeScape UI. The Acer W4 is kitted out with Mango, the latest iteration of Windows Phone 7, which introduces a host of new features such as better integration of e-mail, improved multi-tasking features, and an updated Internet Explorer 9.

While new platforms typically bring more innovation, older platforms are far ahead in terms of customizable apps, and Gingerbread is no exception.

Winner: Sony Ericsson Xperia Arc S


The processing power and beefed up RAM should allow for better multi-tasking, and the quality of its 8 megapixel camera makes it serviceable for pictures on the go. Furthermore, the quantity and quality of apps on the Android Market make it far more attractive than Windows Phone 7 despite its improved function with Mango. It appears that unless the folks at Acer are willing to be aggressive with the W4’s price point, the bare minimum device will offer little in an already saturated handset market.

The Sony Ericsson Xperia Arc S outpaces the Acer W4 in both hardware and software.
