Why not just get a USB flashdrive? - also known as a memory key or jump drive. These are the modern-day equivalent of a floppy disk - you simply plug it into the USB port of one computer and your PC will recognise it as a new hard drive. Transfer your data to it via your file manager (eg Windows Explorer), unplug it, plug it into the new computer, transfer the data to the new computer.
Simple, fast, and no need to mess around with cables, networking and so on.
Flashdrives are also great if you need to move data around - eg if you have files you'd like to work on in different places, or which are too large to send by email. They come in up to 4GB or more now, but 256MB or so would be sufficient for most users.
Just as an example,
www.outpost.com offers a range of sizes and prices - see
here . There are 256MB drives by Memorex and Kingston for under $30 plus shipping. If you prefer to walk into a shop, Staples currently has a 256MB flashdrive for
$30 , and BestBuy has a
Memorex 256MB on sale for $29.99.
