We were once of the opinion that garlic bread was the future. But now, we're convinced that the future is, in fact, digital vending machines that let you rent or buy movies when you're out and about.

Unleashed by the brilliantly named Digiboo over in the US of A, the company describes the service as "the easiest and most convenient way to stay entertained while you’re on the go".

The premise is fairly simple. Digiboo offers up "today’s hottest movies" and you simply whack in your USB flash drive and transfer the movie that you want after paying with your credit or debit card.

Movies cost around $4 to rent and $15 to buy. And the catalogue is indeed chock-a-block with new releases such as The Ideas of March, Drive, Contagion and Friends With Benefits.

There's no HD action at the moment unfortunately - although the company says it will look into this if the initial launch proves successful. Instead, it's SD movies with files sizes around 1.8GB that will take around 2-5 minutes to transfer with USB 2.0, or just 20 seconds if you tap into the USB 3.0 capabilities.

DRM is on board and and there's a pain-in-the-bum sounding preregistration process that you'll need to embark on in order to play your content without having to connect to the web first. It's Windows only for no;, Android is coming soon, apparently.

The initial Digiboo kiosks can be found now at Minneapolis–St. Paul, Portland and Seattle-Tacoma international airports. The plan is to have 7000 in place by the end of 2014.
