Sadly, it\'s naive to think that a community can make a tech product more popular when the company behind it doesn\'t care. History bears me out here. There have been plenty of products in the same position with a vocal and loyal fan base but an indifferent company. Examples include Amiga, OS/2, and Newton. In all those cases there was a huge organized community marketing effort, but the product line eventually died anyway. (anyone remember Team OS/2?) and most of those communities were much bigger than the Zaurus.
The only difference between the Zaurus and the aforementioned examples is that part of the Zaurus infrastructure is open source. Open source has slightly different market economics than closed products. IMHO, the people who want to promote the Zaurus and make it more popular need to press this advantage for all its worth. The best way to do that right now is to support the development of OpenZaurus. Having a rock solid completely open replacement ROM, which matches or exceeds the Palm and PocketPC in terms of features and polish would stimulate additional interest in the Zaurus.
Supporting OpenZaurus has an additional benefit. Because so much of OZ is made up of components from projects like Opie which work on other embedded Linux platforms, even if the Zaurus as a product did eventually die, the fruits of development would live on.
