As I noted, OSX has a UI I hate, and regardless of it's core, it's still burdened with Scrapple's worthless junk. Also as I noted, I haven't found any tasks I need to do that W2K hasn't handled with no issues. Be it CAD, CNC, photo and video editing, etc. all do just fine on W2K.
Probably does. Perhaps some day I'll find something I need to do that Windoze can't handle just fine, until then I have no need for the extra overhead of running a different OS just to be anti-windoze.
Yep. I deal with a fair amount of VMS (OpenVMS) which pretty much invented memory management and scheduling.
TSRs pretty much went out with Windoze 3.11.
