Well you are in the PowerPC section of the forum..
People here obviously have some interest in PowerPC. Good thing we are not clueless like you.
I guarantee I could get more done on my G4 than you do on whatever intel hunk of crap you have.
Any other senseless remarks that do not assist the original poster at all?
Dear zen.state.
I do know, that I am in the PPC Mac section.
Until the beginning of 2008, I used an PowerMac DP 1.8 GHz, 4 GB of RAM with an Radeon 9800 graphic card. It was a fine machine for my everyday illustration and DTP work, till the day, the logicboard died (the second time, since I did buy the computer in 2004).
But since Apple switched to Intel, I had too. New applications are comming out for x86 only and not for PPC anymore (you should thank God - and not Steve - that there are still some developers, who maintain their Universal Binary apps with PPC code). But these applications will be (or are already) more and more in minority in the future.
That is, why I do not recommend buying a used (especially liquid-cooled) PowerMac computer in the - now - second half of 2010. The problems are mostly the spare parts if something goes wrong and that means, it can become very expensive.
Sure, many people can work with old applications and make great things with them (even better, than most, who are just following the trendy things). But, nothing lasts forever. And everybody of us is soon or later forced to upgrade our belowed computer, technology, step away from it.
What would you do, if let say, Apple would one day tell the world, that they will not make any computers anymore, just the iGadgets. No more MacOS X, just iPhoneOS (or whatever it will be called)! Would you switch to Linux, maybe Windows?
I was (am) still mad, that I had to buy some application upgrades, because some of the older PPC applications, that I used everyday didn't work on the new Intel Macs. But this was the only option in that time (I don't buy used computers anymore, because of the very negative experiences, I had with them).
