That very much depends. If you want to use the media in various different
computers, you're probably right. If you intend to use it only in your own
PC or a compatible DVD-Recorder, the advantages of DVD-RAM may easily
outweigh the disadvantages.

and the drag-and-drop
capability is trivial. You'd surely be using at least a simple backup
program anyway. (And for that matter, you can drag-and-drop to DVD-R
or DVD+R anyway.)
But you can't use them with random access like a hard drive -- which you
can with DVD-RAM.

In 10 years, you will have much more trouble reading a DVD-RAM disc
than you would a more standard format. That's an important
consideration for archival backups.

There have been many reports yet of DVD+-RW media that was not readible
anymore after only a few years -- I'm in doubt that you can rely on being
able to read those discs in 10 years either.
DVD-RAM media recordings are expected to have a longer durabilty than DVD+-
RW.
