Looks like help is on the way - as MS / Bill Gates thinks it's confusing too, see:
Microsoft's vision of the business PC

Microsoft's research shows what we all know to be true -- that the different power management modes of sleep and suspend are subtle and confusing. Users want a computer that turns on and off immediately, the only two states that matter. There should be no latency between the two, and the state of the machine should be preserved.
Security from power outages is also very important to users, so Athens has to be able to put itself into the 'off' mode with state preserved even if the mains goes away.
