Jpr,
It's been awhile since I used laplink, but I thought it used the serial ports. The first time I used it (late 80's early 90's I needed the null modem cable; but I didn't think I needed the null modem for the version I got 10 years ago.
Nice to hear that it now uses usb ports. That makes it even easier.
Amp,
If you just need storage for the one computer - disk drives are pretty cheap nowdays (newegg.com has Maxtor 30 gig for $48.00 and a 40 gig for $52.50).
But, on the other hand, shared storage can be good if you need to share the data between both computers and it should be cheaper to setup than $50.00 plus shipping on a disk drive.
