512 is absolutely perfect for regular use.
256 is JUST FINE regardless of what people may say, but yes you'll be paging like mad once you start opening a lot of windows.
128 is also doable (did this with my ex-girlfriend's PIII 700 MHz system) as long as you'll only ever be doing ONE task at a time and pretty much running nothing in the background.
People on these forums are obsessed with memory and don't understand what you can actually get away with, don't listen to the majority of them.
For your purposes I think you can actually pull off 128.
