I used it a few weeks ago when I upgraded from a 20gig to a 120gig and it wasn't bad.
It took a while for it to recognize that the USB transfer cable was plugged into my 360 (have no idea why that part was so hard) but once it finally realized I did have my cable plugged in it was easy.
You just make sure all USB devices are unplugged (including wireless adapter), inset the disc that comes with it, plug in your new hard drive to the USB cable, and then follow on screen instructions. It's pretty easy.
I think it took about an hour and a half to copy everything but I actually just started the process and then left for a few hours and came back and it was all finished.
