I miss MS-DOS (well, perhaps "miss" is not the right term as I drop to command line to do everything Vista sucks at, but I think you know what I mean).
I have fond memories of MS-DOS, Logo, Basic, and constantly swapping 5 1/4 110 KB floppy disks.
The sad thing is I still remember some of the command prompt keystrokes. CD/ this or that directory. DIR to get the listing of files. Maybe DIR *.exe to weed out the chaff.
I still remember commands I used back in the day too... anyone remember "arj a -v1440 *.* filename"
oh hell yeah, and then having to keep track of up to a dozen 3.5 floppies (numbered in sequential order) so my precious random document or warez file could be backed up or shared.
I don't miss MS DOS, the company that I work for still maintains ancient programs on it. Borland C 5.0 can bite my shiny metal ass. 640KB is only good for just so many programs.
