But you have to admit, teaching them dos is alittle extreme. Their is no real reason for them or any other kid to learn it other than nostalgia. its not gonna stop me from trying though.
I'm glad you're still trying. I still find reasons to use DOS these days, though folks not as nerdy as me probably would never need it.
Just in the past month I discovered ffmpeg, an awesome open source, command line video conversion utility that I built a series of batch files for, based on the type of video I was converting from and converting to. I do a lot of video production and use Premiere CS5 for editing. Unfortunately, Premiere is pretty picky as to the formats it's natively accepts. Thanks to ffmpeg and my batch files, I haven't come across a video source file I haven't been able to convert to a format that Premiere happily works with.
So to make a short story long, there are still plenty of uses for DOS these days, in niche markets.
