I'm in the market for a first time Mac laptop (see thread in buying help discussion) and was looking on Ebay. I found the old school iBook, the colored ones and saw they start at $50 and some go for $200. I also saw some that were less than 1 ghz for $500. Why do the archaic computers go for so much? Is a Mac 300 mhz faster than a pc 300 mhz? I'm really confused.
