- CD-ROM writers are becoming increasingly cheaper. It just takes some time to
- do the actual copy. We want to use it for backup purposes; TAPE is so
- un-filesystematic, DAT is nice but CD-WORM is far nicer, since you have the
- actual files readily available and it is even cheaper than DAT! Now let's see
- about the new CD format.

- If you MUST use a dongle, please make sure that:
- - It does NOT block anything that uses the port for what it was designed for;
- - It should be possible to combine more than 1 dongle for the port.
- Dongles are a pain, we have too many of them and it will really decrease the
- intention of running the program; to switch dongles you have to powerdown.
- Please don't use a dongle. For example, on the PC, we bought TVPaint 3.0, and
- got a dongle which actually INTERFERED with the printing (Win95). That's
- really UNACCEPTABLE, especially since you've paid around $1000 for a package
- which then is in practice unusable just because of the stupid dongle. Be very
- careful about the choice of ANY dongle.
