I shall need an additional external hard drive soon. It will have to be USB2 so that I can swap it between machines. A couple of my local suppliers (one of which is Staples) have neat looking Iomega 500GB drives for just under £100. I have looked at one that a friend is using with Vista on a PC and it seems to plug and play without any problems. I am inclined to buy from Staples because I have had good experiences with their customer services. Any alternative ideas?
