What is the similarity shared by a wok and a vest? [br] [originaltext] Google

Google’s Nexus 6 is supposed to be a phone, but it’s practically as big as a wok. Put it in your inside jacket pocket and it looks as if you’re wearing half a bulletproof vest. Phone sizes are getting bigger faster. " It took five years for the average screen size to get from three inches to four inches, but only two more to get to the current average of five inches," notes Alex Barredo, who analyzed data on 7, 000 phone models.
   What’s driving this? A younger generation, in particular, is using the phone for almost everything that formerly belonged on the laptop: Web searching, Facebooking, movie watching. So it makes sense that they’d want a larger screen, as long as it can awkwardly make a call in an emergency, like when they have to ask their father for money. At least that’s been my experience.
   But the trend can’t continue or phones will soon end up as big as laptops. And then some college-age genius will have an epiphany that it would be really cool to have a connected device you could carry in your shirt pocket, as if that never happened before. Then we’ll go back to square one.
