That is for you rich people :-) Not everyone can afford the latest and 
greatest server hardware. There are tons of older servers out there. I 
still manage some servers with only 2GB of RAM and some of their 
motherboards accept a *maximum* of 4GB. Those precious few GB are better 
used with a 32bit OS, don't you agree?
