It's lagging seriously in the performance stakes. If you
Sparc T1 (Niagara chip) are design to be small (so it's cheap and use less power) with 1 pipeline as PowerPC. It also include 4 threads support, so reactivity could be high. The challenge is not to have the maximum performance. But to have the power of a 1 Ghz athlon during 10 hours at least. I consider that any Office application run well on a 1 Ghz athlon. With 100 Whats.hours battery, 10 hours means ~10w. So 5W for the cpu, that's very small. PowerPC could be a good candidate but SUN chip is open source, that's not the same price and you can optimise it for power consumption and not power (target 800 Mhz instead of 1.2 Ghz). > want portable, use either PowerPC or Arm.
