Photos: Wireless fest, featuring Barcelona

BARCELONA, Spain--After attending way too many trade shows in Las Vegas over the past 10 years covering technology, I'm delighted to come to Barcelona for the annual GSMA Mobile World Congress. Vegas might have the Strip, Sigfreid & Roy, and amazing buffets, but Barcelona's got it beat with Parc Guel, Gaudi, and the freshest and most delicious seafood I've ever eaten.

You can't come to Barcelona without checking out the buildings and parks designed by the modernist architect Antoni Gaudi. This is a photo of Casa Batlló on the Passeig de Gracia, one of the two great buildings designed by Antoni Gaudi on Passeig de Gracia, the other being La Pedrera. The local name for the building is Casa dels ossos (House of bones) because the outside looks like a skeleton. On Monday night, Acer held a press conference here where the company unveiled eight new smartphones. Check out Bonnie Cha's coverage of the event.
