Watched a demo of this on QVC yesterday. Quite impressive. One cable only for the power supply, until you start adding printers, scanners etc. Demo was of a 64 bit system instead of normal 32 bit. So drivers may be a problem if you intend using kit you already have. Must say they were selling like hot cakes yesterday. If you can get a demo and try it out yourself so much the better. Currys are stocking them at the moment.
