Note the difference; every time M$ “upgrades,” programs fail, data is lost, and old machines become obsolete. Every time Mac OS upgrades, old aps still run and old machines run faster.

When Apple "innovated" to Intel chipsets, they required that their users buy "upgrades" to all of Apple's professional software except for iLife, Safari and Mail. See this from Apple.com:

The old sw still ran. Just slowly.

Rosetta was intended for those applications that did not have a universal version. The Apple Pro applications were ready from day one of the Intel conversion with universal versions.

Keep in mind that these ARE professional grade software... the software that people make money with... and those who do use them to earn a living would not hesitate to upgrade to increase speed and therefore productivity. These are the same people who don't blink at buying a $10,000 maxed out computer because it is more reliable and faster than a $5000 computer.
