Mac
Today i tried to get quake 3 and zdoom to work on my friend's Mac. i spent a total of 2 hours trying to do both, and i had to go through so much, but even then, i never got both working. i was able to get doom legacy working, but i wanted to show him all the cool and funny doom mods, like simpsons doom, and you need zdoom to run that, and there is no zdoom port for mac.
Quake 3 there is a port, but it only works for OS9 and not OSX. i wonder why it's not backwards compatible. i spent a long time trying to get it to work, i ALMOST did it, but then i had to go, i never finished downloading the other 2 programs needed to upconvert it to an OSX format, lol, but see how much work you need to put into a MAC just to get it to do something a windows can easily do?
Vista
I dont mind it, but i like Xp better. im more famaliar with XP and it seems easier for me. i just like how most drivers made for XP also work on vista, but most Vista drivers are made for Vista and Vista only. At the moment, Xp has more compatibility (and probably always will). Vista is and will come close in compatibility, but i still like XP more.
