I'm looking forward to hearing the answers to this one.
In general, laptops have their own special drivers, so you usually dont want to CLONE your main hard drive, but rather you usually just want to copy your data files.
In this case, if the source laptop has a DVD RECORDER (many new ones do), it's a matter of simply locating your data files and burning them to dvd and then putting the dvd into the new laptop and copying them to the new machine.
If the source laptop does *not* have a dvd recorder, you have some other options:
network lan copy, special software and usb connection, or what i use, an external usb hard drive.
The nice thing about using an external usb hard drive is that it's very useful for general backup functions. So you'd connect it to source laptop, copy all your files to it. then connect to your new laptop, and copy from it to the new laptop.
