Back at the IFA 2011 in Berlin, there was a smartphone running on Windows Phone Mango displayed at Acer's booth. The smartphone was called as the Acer W4, which apparently will be Acer's first venture into the Windows Phone world. In France, it seems that the W4 was announced in France as the Acer Allegro and will be sold in the country for €299. So, what's up with this smartphone? What is it's selling point or should I say what makes this different from the other Windows Phone 7 smartphones out there? Acer put their fast charge technology in it allowing you to charge the smartphone 2.5 times faster than what the industry does. Anyway, head over the break for the device's specs.
