I've got a new computer running windows 7 and I want to transfer stuff from my old XP one...mainly photos and files I think. I'm not very tech savvy and it looks like the easiest way will be to use an "easy transfer cable". I've searched for these and they seem to range hugely in prIce, it is worth spending the extra to get a named one like belkin or are they all much the same? Also are these "easy" as the name implies????
