yeah yeah you probably say that there is such question in topic about RAM usage.
but i did not found some usable explanation for this.
can you tell the people why skype using so much RAM???
OK, i understand it is 21 century, powerful machines for powerful programs.
but come on - lets be serious.
in my case skype use 100MB RAM in idle - that's just stupid!!!
it is not like i am do not have enough RAM. but still.

my personal explanation about RAM usege is that powerful pc hold up skype network around your neighborhood
so if you have old pc, skype do not use much of memory.
in my case machine is pretty powerful so skype is using my as local server for him self...
some one wants prove otherwise - you can try!!!
