I needed a new PC. I started asking friends and relatives what I should get. A few said Macs are far superior to any PC. I've also had problems in the past with viruses and such and they said I wouldn't get any with a Mac. They said the speed was better, etc etc etc.
I then went to the computer store (Best Buy) and asked them. They spoke SO highly about the iMac that we ended up getting it.
I have ZERO experience with Macs before my purchase. The guy at Best Buy said it would take me about a week to get the hang of it. HA!
It seems clear that you had no inclination to learn a new operating system, and nothing special that you needed a Mac to do. Because of that, I think I'm probably going to be the lone voice of dissent and recommend you take your iMac back to Best Buy and get something with which you can be productive immediately.
Moreover, I believe your friends and family did you several injustices. First, by not considering your lack of need. Second, by not fully evaluating your situation and desires. Third, by not being there to help you start down the path on which they set you. And fourth, by implying that Macs are without vulnerability (they're not!).
And the Best Buy goons will sell you anything that you appear to have a twinkle in your eye for. "I heard good things about [premium priced] Macs. What do you think?" "Well, ma'am, Apple [cha ching!] makes a wonderful product..."
Don't get me wrong, I think Macs are the greatest. But if you don't
want to change, if you don't enjoy the thrill of learning something new, then you're in for many many more frustrations in the coming weeks and months. Why do that to yourself if you don't have to?
Good luck.
