Yes, you have a lot more RAM than necessary to run those few apps. Same 
here BTW.

My desktop doesn't support suspend to RAM but suspend to disk. If I want 
to suspend I only have this one option.

Suspend to disk means that the entire machine is switched off (including 
disk) after the memory contents is written to disk. OTOH, suspend to RAM 
means that there is still some power needed to keep the RAM alive.
