While this seems to be a battle of anecdotes, everyone I know who owns a smartphone uses it as their primary non-work email device, Facebook device, browsing device, LinkedIn device, etc. Many home personal computers no longer get turned on. It isn't a cell "phone" as much as it's simply a portal computing device.
It seems that HN now automatically applies a -1 to my posts. Add this to the cowardly slowban and I'm done with this site: The users have gotten stupider, the administrators are halfwits (I'm talking about you, dang), and its utility is gone.
