In addition to the financial arguments given elsewhere (the cost of upgrading hardware to run OS 10.5), I can give another argument for not deprecating OS 10.4. It is quite common for a bug to show up on one platform, but not on another. In many cases these are real bugs, which could affect any platform, but just happen to show up on one. Then, at a later date, they show up on another. I recall chasing a bug which only happened on a quad processor IBM RS 6000 running AIX, despite working on numerous other machines including a Cray, Suns, Linux PCs, an SGI Octane, HP Visulize C3600, and countless other bits of hardware. When I finally tracked the issue down on AIX, which was due to a locking problem in my multi-threaded coded, I realised it have shown up on any platform, but just happened to show up on AIX. No doubt, some time in the future it would have shown up on other hardware or operating systems. Note cliquer also has issues on Solaris. http://sagetrac.org/sage_trac/ticket/6852 which might be an indication the code is not as well written as it could be. It uses SCons, which seems to cause problems on lots of code as far as I can tell. As reguards to http://sagetrac.org/sage_trac/ticket/7107 'sage does not build on ppc os x 10.4 anymore, failing with mpfr' I would note that 'internal compiler errors' can be a result of a library not being found, which can sometimes be fixed with LD_LIBRARY_PATH.
