With the introduction of the iPad from Apple, tablet sales have skyrocketed over the past couple of years. Online retailers have jumped on the bandwagon by introducing versions of their online storefronts that cater to people who use tablet devices.
The term "Couch commerce" is derived from the fact that many people will be sitting on their couch (or in the bath, or outside on the balcony, etc) while they do their online shopping this year. The introduction of the iPad and similar tablet devices has completely changed the buying experience forever. People no longer sit right in front of their computer screens, highly focuse on their task to find best deals.
