"Just 24 hours after Asus unveiled its padfone, ECS is toying with an idea that resembles the Asus PadFone — in a nutshell, a tablet that becomes a docking station for your smartphone just by slotting it at the back. While the Padfone works only with Asus' own smartphone, the ECS model will be open to other models and the one we played with was physically compatible with the Apple iPhone 4. Wu reckons that the accessory will appeal to users because it doesn't require them to ditch their existing handsets and will be compatible with future models using what Wu described as 'simple upgrades.' The tablet will work across platforms; Windows Phone, Android & iOS which should include the iPhone 5."
