How much swap on laptop?

I think that rule was more valid a few years ago when ram wasn't quite so 
available. Now most new systems have a lot of ram, and the factor of 2 is no 
longer quite so important. With 1G or above I would probably just use the 
same amount of swap as ram, not twice as much. As you say if you really need 
more swap, you would be much better of shoving more ram in...

Yes, I did wonder about this when I upgraded. I might be wrong but reading 
around I wasn't sure if suspend could handle a swap file though ?

I told myself I would look into it if I had problems. None as yet so haven't 
bothered :)
