oh please. I had Tiger on 512MB with my MB, it was so slow I have to update it to 2G. and leopard is asking double the minimum memory requirement of Tiger. 512MB for faster leopard? are you serious?
at the same time, I did have my Acer with 1G memory with Vista. Tell you what. It runs fine.
how about you go ahead use 768MB with your leopard, see how long you can take it.
want to make some decent argument? then lets get some real comparison first, not guess this, imagine that.
You want to show leopard is faster in majority cases (since thats the basic definition of being "faster")? get some test package, put on similar Hardware equipment, and run them side by side!
