The best thing for me is that you don't have to worry about getting directions or knowing where you're going to go. There's also the ability to instantly pull up info--you never need to forget who that actor was, and discussions don't get derailed by pointless quibbling over facts that could easily be looked up.
And yes, you can browse HN on the toilet. Life is good.
Would be interested in answers to that, too. I haven't joined the fun yet, but I wonder if there really is anything life changing about it (yet)?
