What are the most important things to consider when choosing a new gadget? Its features, the fact it’s the first of a kind, the way it looks and user reviews are all certainly important, but for many people it’s the price.

The cost can make or break the success of a gadget. Many pieces of technology succeeded not necessarily because they were the most ground-breaking or had the best features, but because they went on sale at a price affordable to regular people.

In the quiz below we’ve picked 12 pieces of technology and we want you to guess the original price. Some went on sale at ground-breaking prices, while others were expensive technology firsts. Good luck!
