Tech Digest has reviewed the new "anorexic" Samsung D900 "slider phone". ' Samsung's new Ultra range is designed to illustrate just how much technology they can fit into a slim phone design. So, whilst they've now got the skinniest candybar title, the slimmest HSDPA phone and a host of other accolades, they haven't skimped on the specs. The D900 was the first of these to be launched, featuring a sliding design and measuring just 12.9mm in width. And yes, it's the world's slimmest slider phone. Available free on contract, it's in the shops now.'
