Tablet computers are becoming increasingly popular in the technology world, especially with recent releases such as Apple's iPad Air, Samsung's Galaxy Note Range and Google's Nexus devices. With the development of tablets comes the development of tablet trade-ins/recycling - and this is what this infographic hopes to spread awareness of. The infographic was put together by leading gadget recycling comparison engine CompareMyMobile.com - who compare over 40 UK recycling companies on price and consumer reviews. They say that tablet trade-ins are increasingly popular, especially certain brands. Data on the graphic shows top tablet brands and models being traded-in as well as the the most valuable models and those losing value most quickly.
