1. I can't afford to buy a Mac now (basically because I can live without it)
Would you like to sponsor me a MacBook?
I can't afford one either, that is why I installed a patched version on my computer. But if I did I would buy one. Macs are more for fun than for real work, because you can't do real work when all those shiny things distract you.

2. I don't think they produce PowerPC based Macs anymore.
Yes, I think you are right.
