Not really. It's just that a lot of newer software is going to arrive
on DVD media--not just Fedora. Trying to sort out some other mechanism
to load software can be a royal pain (getting a CD/DVD ISO image to
install on a thumb drive being just one of them). Having an external
USB or firewire DVD drive can be very handy for machines that don't have
them.
For example, we have about 800 Dell 1850s and 2850s that don't have DVD
drives. If we need to install software on any of them and that stuff
comes on a DVD, that's a problem. Network installs aren't always an
option in our business. So, we wander over to the machine with a
USB-based drive and do what needs to be done.
I've mandated that we have two USB-based drives in each data center...a
500GB to 1TB USB hard drive (for immediate backups) and a USB CD/DVD
rewritable drive (for software installs, archival backups, etc.). I
found one company that actually makes a 500GB drive and DVD+-RW in one
box. We have two of them. No, I can't recall who makes it.
