One of my coworkers has a tablet, he seldom uses it in that mode, but it seems to work well when he does. 90% of time he uses it just like any other laptop. I saw the same slide and I'm curious whether the 5 watts is typical or max consumption. Currently while doing light stuff and the LCD kicked down a couple of steps my 1.6 Pentium M only takes about 12 watts for the entire system so I suspect it's not pulling much more that right now. Now if I kick off a render that jumps to about 18 watts, so if the 5 watts is max consumption that will be a very nice boost for battery life.
