Another thought:
There’s no kiyum to typing on a computer screen. It isn’t “really” there. On the disk it’s just a pattern of magnetism, and on the monitor it’s just a pattern of chemical dots which have been momentarily activated by an electron beam.
BUT printing out is another matter. Then it has a kiyum, like anything written or typed on a machine. I don’t print anything out unless it’s a davar ha-eved or a need for the chag (e.g. grocery list).
Anyone else have any thoughts on this?
