How do you know your computer is doing a lot of work?  Most of the time the key indicator is hard drive heads clattering away ever so often as information is written and read from the drive. Well, as we move to 64-bit operating systems with more and more RAM and solid state hard drives the computer's operation will become virtually silent.  No longer will you know when the information is being paged out or your anti-virus software is chugging away aside from the system monitors and performance logs.  The silent laptop is kind of exciting and eerie at the same time.

The other crazy things is having a 17inch laptop with screaming specs last on battery longer than 7 hours.
