<p>Firstly, DVD-RWs are not the best. Sure, they hold a lot more data, but most transfers you do will be small (i.e. Word documents, like you say). Putting in a DVD, burning, and then putting it into another computer (which also must have a DVD-ROM) and reading it takes far longer than sticking a USB in, copying files in a couple seconds, and sticking it in another computer for reading.</p>
<p>I never buy DVD-RWs or CD-RWs. When I want to put large files on discs, I just burn them permanently on CD-Rs or DVD-Rs because chances are I may want them at a future time. If I want to transfer a lot (5+ gb) of data from one computer to the next, I will connect them to the same network and then transfer, which is the fastest method. I don’t think DVD-RWs are very useful outside of doing regular backups of large quantities of data.</p>
<p>And as far as diskettes go…well I don’t think most of us have such ancient computers. Every computer I’ve made over the last 5 years or more has had a USB port.</p>
