I'm twenty and still remember how to use MEMMAKER. Oh the joys of 640k.
I use the command prompt similar to yourself as well. And because of that usage, Winkey+R, notepad or calc or iexplore has become muscle memory.
I've had some shitty experiences with Aliant employees as I'm from Halifax, but nothing that would drive me that far. Christ.
I have a theory that it's impossible to prove anything, but I can't prove it.
