Still using Win Xp SP3 as daily driver here ... (have others, couple Win7 boxes, Win10 box, dual boot Ubuntu/Win Xp box) but everything I need on a daily basis is here on a 32 bit Core2 Duo 45um running at 3Ghz w/4GB of ram ...
The problem is getting a browser that works; Mypal68 works for me.
I missed my XP box. Best Microsoft operating system by for. The XP machine died. Win 7 is at least functional on a 12 year old machine.
