I'm curious to hear what your setup for the intervening 20 years has looked like. Did it involve moving to GNUstep when NeXTSTEP was no longer viable, or is it something like, you came to NeXT by way of e.g. Sun (or something) and never had any particular affinity for the NeXT environment and so your setup has always been Linux/BSD/Solaris...?
My skills have always centered around OS and Database. I've mostly worked on UNIX then Linux at command line. Lots of vi and compiling over the years. I'll use whatever desktop is around...and, practically speaking, that has usually been Windows at the Fortune 50.
