Klaus, the thing is that to fit into the thin-and-light package, the CPU, at its full clockspeed, must not exceed the 25W thermal limit. 30W might be acceptable at the time. The current specs suggest that it´s still ways off. Don´t confuse this with battery life/average power consumption. Dothan is currently speced at 21W TDP for 2Ghz, which is pretty much the benchmark. I don´t think A64 can reach that. But, there are other form factors, those will come first.
