Alright, first, I want to thank everyone that posted on my other iMac thread; my dad and I are now certain that his first computer will be one of the CRT iMacs. However, the current price of AirPort cards on eBay and the need for an adaptor raises a question in my mind. Would it be more prudent to just get a USB wireless network solution? Are these generally compatible with Macs and as good as AirPort cards (or are AirPorts worth the $100+ that they are selling for)? Does anyone have any suggestions on which to buy? I'm going to try to find an auction that includes the card, but that might not be feasible, and I would rather spend the $100 on a memory upgrade to keep OSX running smoothly, which brings me to my next question: How smoothly can I expect OSX to run on an iMac? I'm thinking that 512 mb of RAM is a minimum, is that about right? And how fast of a processor should I be looking for? He only emails and uses the internet, for now anyway, so would an early 233 mhz or 300 mhz be sufficient? How does processor speed affect OSX? (I'm of course wanting to get one of the late model 700 mhz computers, but if a 1st or 2nd generation processor is sufficient, I'd go for that too). I know this is long winded so thanks to anyone that helps.
