Thanks Nils, it's good to have confirmation, so, if someone, like me 
finds no use for 'suspend to disk', on a desktop, or even on a laptop,
while 'suspend to RAM' is okay, say taking a 5 to 10 min break; and any 
longer breaks like 30 mins would prefer to shut down completely and 
restart slightly longer than "suspend to disk', it would not serve much 
purpose to have a huge swap partition? Of course, if his computer can 
handle it. Naturally, hard disk space is so big now it doesn't matter to 
have a good sized swap, in case somebody has found some more interesting 
things to use it for.


Thanks again for your feedback. Appreciate it.
