The Mobile World Congress 2011 took place this week in Barcelona, featuring keynote speakers like Sir Martin Sorrell and showcasing some the world’s most innovative mobile technologies.

With more than 1400 companies in attendance, the conference highlighted everything from smart phones to tablets to new applications for these proliferating devices. Even good old Angry Birds found a place in this week’s festivities, taking home the awards for Best Mobile App and App of the Year on the Apple platform.

It’s no surprise that tablets dominated this year’s conference. Acer launched its new Iconia tablets, which critics hope will have a more reasonable price tag than some of its competitors. HTC also revealed its Flyer model, which CEO Peter Chou claims is more than just another “me-too” product.

More than a showcase for new devices, the event made headlines by uncovering some controversial opinions about the world’s most powerful tech companies. For example, AT&T’s CEO found himself with few positive things to say about Apple’s customer service. On a more positive note, Microsoft CEO Steve Ballmer discussed the benefits of the Windows Phone 7 and boasted about the positive reactions it has received.

Smart phone pioneers Research in Motion also presented some new developments with Blackberry, unveiling a new app that manages travel itineraries. And Mark Zuckerberg a made a cameo via video recording to put the rumours about a Facebook phone to rest.

Throughout the conference, members were kept well informed via MWC’s  Twitter feeds. We can only hope that this year’s countless innovations will give us plenty to talk about on the mobile front until Mobile World Congress 2012.
