This isn't Craigslist, but it's a pretty ridiculous example of bad deals of PowerPC Macs.
So I was in Kerry visiting family over the last few days and I was staying in a Hotel in Tralee. I went into town to do some clothes shopping, when I passed a small time computer parts shop. Intrigued by the iMac G5 on the windows I went in, in the hopes of maybe finding a well priced addition to my collection.
The owner was an Eastern European dude and I said hi to him as I entered. I asked if the Mac on the windows was for sale and he said 300! I thought it was maybe an early Intel iMac but he assured me it was a G5, and in fact it was the oldest kind of G5 iMac. I mentioned that it was a little steep...
Trying not to smirk too obviously I went over and looked at a 2004 iBook on a shelf of laptops for sale. He wanted 160 for it!
Worse still he even had a "2007" sticker on it which I was sure to correct him on oh so politely. I booted it up, to see if it was working and when I was going to quickly turn it off via the power button he made a big thing of "that damages the computer" in the usual IT condescending way. I said nothing and obliged him, despite questioning his knowledgablity of computers in general in my own head. It's the only way I turn off my Apple II Plus or Macintosh 512K and they seem to be still functioning
He said the 2007 sticker was a mistake, but in sure he wouldn't tell the next poor guy who didn't know any better interesting in blasting 160 on something this ancient. Right beside a 2009 MacBook, it looked no different to most people. Intentionally misleading people I'm sure.
He was aware of the obselecnce of the PPC platform but said that they would still make good beginner machines. I might agree, but not for his prices.
I eventually offered him 50 for the iBook and he just shook his head and didn't even make eye contact
All in all, the whole place felt as shady as Simeon's car dealership from GTA V.
