In what system are you talking about? A desktop? A laptop? A newton? You'll get radically different answers for these three radically different environments. I find it hard to beleive that a 10 watt pentium in a PC laptop is only %20-- that means that the total budget for hard drive, display, etc, is 50 watts. How can you get 3 hours on a 45 watt-hour battery if you're drawing 50 watts? Obviously, you're drawing 15 watts. (Correct me if I'm wrong, but Intel's mobil pentiums take up 8-10 watts) If you reduce your usage on a 400MHz laptop from 15 watts (with a pentium) to 6 watts (with a Crusoe) your battery life goes from 3 hours to 7.5 hours in a 45 watthour battery. Ok, so its a 2.5 times improvement. I think that's enough to make it killer in the marketplace. (And I think a lot ofp eople will build devices that only add 2 watts to the CPU's 1 watt and last 7 hours on a 21 watthour battery.) BitGeek
