why do this at all.

Most mission critical software is now avail for leopard as a free upgrade.

Not to mention the fact you will have to eventually move forward.

This also does not make sense from a developers stand point as todays iMacs are more powerfull than those of the Tiger era.

While yes this does make them better suited to use tiger as it is a bit clunkier than Leopard it also prevents you from getting acurate test results.

Yeah you can limit the hardware for the purpose of a test but that is far more anything than just hitting up an apple retailer for an old tiger based mac which accurately represents the power of its previous owners).
