What if you could tell who's at your front door without leaving your comfy spot on the couch?  Then, what if you could unlock the door for them?  Turns out, you can.

I'm a huge tech nerd; so I love this time of year, because a ton of new gadgets get unveiled at the Consumer Electronics Show (CES) in Las Vegas.  One of the cool things shown off this year was the Goji Smart Lock.

Basically, this lock can tell you who's at the door, show you their picture, and allow or deny access to your home, without ever requiring a physical key.

I sort of feel like this is where technology is headed, so it'll probably be part of every home eventually.  Would you ever want something like this in your home?
