Sony is showing off their concept device, Lifelog camera, a wearable that records still images as I go about my day. It's gorgeous but if Google Glass seems a bit creepy, I can only imagine how people will react to a camera around my neck, constantly recording.
What do you think of the Lifelog concept? See any practical uses?
What is the future for the giant telcos that in the past have been the key players at MWC? Companies like Vodafone and Orange remain the foundation of the mobile business, but only just. Increasingly they are being sidestepped by the big five OTT (over the top) players: Apple, Google, Facebook, Amazon and Microsoft.
All of these companies have grabbed control of market sectors that the telcos tried to "own." Overnight, Apple showed how it was possible to sell games, movies and music via mobile; Google did maps and search.
Now, Facebook is poised to seize messaging and maybe even voice. With WhatsApp confirming the addition of voice calls inside its app, the first and last bastion of the cellular networks is under siege. Operators just need to provide a data or wifi connection and, well, that's it.
And yet Mark Zuckerberg was permitted to use his guest appearance at this week's MWC to boast of how he's going to "help" the telcos connect the next million.
Messaging app LINE is at the show in the Samsung developers pavilion. They've recently announced that instead of selling official LINE stickers within the app, they are going to allow users to create and sell stickers themselves. This sort of market place has worked well for some online social services like IMVU and SecondLife in driving more digital good sales. Is this the start of creative marketplaces for digital goods in mobile-only communities?
