This credit-card-sized 'dumb phone' helped me de-stress and disconnect for the first time in weeks

Here's an experiment: Try to remember the last time you purposely left the house without your smartphone.

If you're having trouble coming up with an answer, you're not alone - and you're exactly the type of person the makers of the Light Phone are targeting.

The Light Phone is the anti-smartphone. It does two things and two things only: It sends calls and receives them.

It doesn't text, it doesn't connect to Twitter, and it doesn't have a camera. All you're able to do with the Light Phone is have your calls sent to it via call forwarding and program in 10 speed dials. Light's founders actually say the phone is designed to be used "as little as possible."

So why would a company build a product it doesn't really want you to use? Easy: To help cure smartphone addiction.

I tested the Light Phone - which costs $150 - to see if I could leave my phone at home and "go Light." It was a lot harder than I thought.
