For most computer savvy users, transferring data between two computers is relatively easy. If you have a network set up, you can share data between two computers. Alternatively, you can simply use a flash drive... but that might not be very efficient if you are transferring a large amount of data. But, for those users who aren't as "skilled" with computers, this can present quite a problem. I have seen countless people burn CD after CD of data to transfer to their laptop, which of course is time-consuming and wasteful.
