It simply takes too long to start up, load the documents I'll need for
the day, etc.  I teach chemistry, and I use my Thinkpad for
demonstrations/presentatinns, course documents, rolls, internet
access/email, etc.  When I open the notebook, I want all my stuff
available - immediately.  Students are waiting!

With suspend-to-RAM, you pick up immediately where you left off, no
waiting for your application to load, for the OS to boot, etc.

With suspend-to-disk (hibernation), it takes a little bit to boot up, but
you have all your applications loaded, running and ready to go.

I almost never just shut my Thinkpad down.  What's the point?

Think of all the power you're not using to start up sevices, etc. each
time you boot. :)

There are only disadvantages if suspend/hibernate don't work. :)
