Nice for a change that unlike the ars technica article, savethenetbooks.com did actually get mentioned as the news source for the court documents. :)
However I can't say I follow the argument that Psion are in the wrong. Intel knowingly and intentionally used and subsequently spread a trademark for which they did not have the right to use. If Psion don't see any money coming there way, and a court ruling in there favour I'd be surprised. Intel should have, and quite easily could have, approached Psion in the first place to buy the trademark in my opinion, or could have simply used something else!
