I've been in Barcelona at Mobile World Congress (MWC) since Saturday.MWC is a trade show for the mobile industry. It's freaking gigantic. I've never been to MWC, or CES, so I've been overwhelmed by the sheer scale of the whole thing.
I spent two days taking photos of what it's like to walk around. Hopefully you get a sense of how big this whole event is.
