Already for a while Intel is claiming to bring a 1Watt chip.Though I heard little of it lately, that chip was said to be enough to do all everyday tasks like checking email, doing word processing and office tasks, viewing youtube and flashfiles...
1 watt is not that uncommon for cellphones, but it is, when it's optimized to do all of the above tasks!
It seems to me to be a close contender to that 'one watt chip' intel is claiming to bring; even looks like the one watt,aimed for Ultra Mobile internet devices (they say including mini netbooks,so I suspect it will perform like the silverthorne Atom processor), will be more powerful than this one.. I could be wrong about this though..
