I think it's sad someone would pay top dollar for 3 year old technology, but hey it's great for us right? I wouldn't buy an old computer with the exception of a current model refurb windows or mac. But my other point is I can build a new PC right now for $1,100 with quad core i7/2x HDDs/6GB ram or pay $400-$700 more for an underpowered/un-upgradable iMac so I can maybe make $500 in 5 years time. Doesn't sound like a fair trade off to me right now. I'd rather have the fastest hardware for the lower price and donate my old one to Uncle Joe so he can get rid of that G4 he still has.
Except with Snow Leopard comes out and it doesn't support non-Intel based Macs you mean? Apple isn't Microsoft and they don't want to be in that predicament of Uncle Joe trying to run 10.6 on his G4. They want you to buy new hardware. I actually applud them for it because this legacy support is what bloats microsoft OS's.
Ok well first off, I think you have to realize a lot of the people that frequent this forum are more computer literate than the majority of computer users. Snow Leopard doesn't add a whole lot of features, it's under the hood which most users will not notice anyway.
You just said you cannot prove it so why are you stating it? I love debating but you have to be able to back it up. My wife's Vista PC I built runs just as good now as it did in 2007 because we take care of it. (She just won't use a Mac I don't get it)
You built the PC, which right off the bat shows more knowledge of computers than the average consumer, but does it run EyeTV, iTunes, and Safari on 1GB RAM?
Finally something we agree on!

Which is where my current frustration comes from. I KNOW I can sell my iMac and build a new pc system for about $400 more if I really felt like it but I just don't want to. (But the knowledge kills me)
I know your frustration, I'm slightly above the average consumer on my computer knowledge, my iMac I got out of my wife's suggestion which would be an average consumer, but believe me I considered some PCs with much better specs long and hard before getting my iMac (first Mac) and 2 years later I think I made a good decision.
You had me until this part. 10 year PC user - 0 Virus. I would love to take a poll as to how many pc users actually got a 'killer virus' that ruined their lives and put this myth to rest.
Ok your 1 anecdote about 10 years virus free, plus mine which is about the same as a PC user, vs my youngest sister in law who got a virus/malware/spyware every other day on her computer and my oldest sister in law who gets one about every month, and keep in mind we are more knowledgeable than the average consumer.
EDIT: Something I just thought of, my wife has also put malware on my XP partition on my iMac before, just by sleeping on the bluetooth mouse with a firefox page open (yeah it's kind of a shady site she was at but we use it all the time awake with no problem-common sense and all) this was after she wanted to use XP over OS X, needless to say she uses Mac OS X now, so something as simple as that can make you convert even if you prefer XP.
