Nope. But that;s because I'm the only one in my group of friends and family that's a tech head. I always point non-techies towards more mainstream products so they don't get all nasty of something goes wrong. Because in their eyes, a Nexus device is "Nexus who??" and they'll just end up regretting not buying something name-brand
Do you think non-technical people would be more inclined to buy a Nexus 5 if they knew both LG and Google made the product? Perhaps Google should just advertise the phone as the "LG Nexus 5" or the "Google Nexus 5" to give people an idea that it's not made by some unknown company.
