Software is still a big seller too.
http://www.CatsMeowSoftware.com has a neat program for Palm Pilots and other types of Personal Digital Assistants
(PDA's) for maintaining saltwater tanks. Freshwater as well.
Whenever I can loosen up some time, I'm 90% done with a site geared towards PDA's too.
Success and Regards... Mike
