I recently bought a new laptop and got a data tranfer cable - similar to the one listed and it was amazing - after 4 hours virtually all of my 6 years of files and programmes were effortlessly transferred from my 2003 laptop to my 2009 one, whilst i went shopping and got on with other things.
Put the CDR into my old laptop, let it install, plug in the USB cables and on my new vista laptop, press date transfer and it does it. After 4 hours it did stop working, but all that i wanted was on my new laptop, so i cannot praise these data tranfer cables enough and it is such a labour saving device.
Just remember to plug both your laptops in and make sure it is not set to hibernate or switch off after 1 hour of inactive use!
