My wife has a Nexus 5. It's still working fine, albeit is sorely lacking in memory. It was completely replaced (or refurbished) once under a Google issued warranty but other than that it keeps on going. I tell my wife that she should upgrade to something newer, but then we look at the prices for new new phones and it's like another mortgage and car payment, yet I see lots of people with flashy new phones. How can they afford them?
