The Wadia 170 iTransport is the first iPod docking device to coax a digital signal out of the iPod (incidentally, my 82-year-old mom loves hers). Till now the iPod could output only a line-level analog signal to docks. How Wadia managed this is a story yet to be told. The company insists that there is no need to pay a hacker to crack the case –- the 170 is Apple-approved. Price: $379.
