Hi,
It is sad to see you recommend a PDF reader that hasn't been upgraded since 2005. It makes me wonder if you have even tried it since "The recommendations are based on ease of use and install and do not reflect the technical merits of the software itself." The available downloads are compiled for PowerPC architecture, which requires a translation layer called Rosetta. In the latest carnation of Mac OS X (Snow Leopard) this layer is not installed by default, which requires a massive download before you can run your new PDF reader. An unexistant recomendation is better than an uninformed one. A much better option would be to recommend skim [1] which was last updated in September and is provided for both architectures.
