Anyone whining about Rosetta : Don't upgrade. There, easy enough.
Anyone whining about fuel prices, don't use it. Anyone whining about rising interest, don't take loans. Anyone whining about the government, move out of the country. (EDIT: In case someone didn't get it, these are examples of similar bad arguments)
Anyone whining about genuine criticism, get better arguments. I'm saying: "It's too soon, the field has not had time to adapt." You're basically saying: "Sucks for you!"
There is a significant PPC app user base with nothing to go to except Windows because it apparently doesn't pay to develop for Mac. Freezing your system is a bad option for a business compatibility with other systems will decrease exponentially over time, the same tasks will take more and more time. It's called fragmentation, and it's not a good thing.
There's a crowd on this forum that'll say: "Good riddance, switch to PC, we'll be better off." Why will you be better off? Just because you will have a forum full of people who agree with you? I think it's sad if progress means you have to lower your expectations of what is possible on a mac. Two or three more years would probably have made a big difference. Peripherals don't last forever but they last more than a few years. PPC-based peripherals are still selling and they are in key positions for many users right now there's nothing to replace them.
So, you either take a bad alternative and don't update, which will lead to ever increasing problems, or you switch platforms to something that won't periodically shoot it's own leg off. But that costs a fortune. I think I might have made a good short-term investment by switching to Apple five years ago, but a bad long-term one.
