Replying to undo moderation mistake.

Good point, sorry, I ment to say people already have Google accounts. My mistake for not being more precise.

Because most people already have gmail accounts and Google makes it painless, simple and usefull. Microsoft makes it painfull, complicated, annoying and useless. I have no idea about Apple ... I had to endure their craptastic MacOS 9 at workplace long time ago and developed very strong hatred to anything Apple since. The only way I'd touch anything with half eaten apple logo is with a hammer.

Could that be a bunch of computers behind NAT using the same external IP or you think those users were genuinely malicious?

One thing to note is, is that people are lazy and they easily forget they've subscribed to lists. I don't know what kind of list you have, but i would advise you to put very noticeable unsubscribe at the start of the list instead at the end of it. IE: i get some mails that i know i have subscribed to, but aren't what they were supposed to be. It would be easy to mark them as spam (people react emotionally to disappointment) especially since they hide unsubscribe options with the smallest font possible at the end of the message.
So my suggestion would be: make it easy for people to do the right thing and they'll do it. If you make it difficult people are very resourceful at doing the unexpected.
Another thing to be noted is that people were "trained" to not click unsubscribe option ("don't click unsubscribe or you'll just confirm your mail address as active to spammers" advice we've heard many times).

Again, I don't know what kind of list parent runs, these are just general observations from the lists I encountered.

I disagree with you ... You can go to any computer store and buy computer for 2500 € and it will play modern games. The only way to get one that can't, would be to explicitly demand something special (ie: server). As i see it Apple is selling their computers as general purpose computers which (especially at that price) includes playing modern games.
There is also another point. Apple prides itself in their customer care, how come the sales person didn't notice someone not familiar with their products and offer advice?

Car Analogy: This is like a person buying an expensive family car and then being upset that they can't drive more than 40 miles per hour. Then going out and buying another (cheaper) brand car and being pissed at the expensive car manufacturer because expensive car doesn't do what any similarly priced car on market can do.

I'm pretty sure Geocities pages don't load anymore. They were closed on 26th ;-)

Wouldn't this kind of errors with identical software indicate crappy hardware?
