I'm not a troll what a guy can't give his honest view of his iMac. Sorry if I have issues with it, yes hopefully it will get easier. But sorry just stating the facts on my apple use this far. Sorry it wasn't all rainbows and sunshine like yours was.
Seems to me that your issues are twofold:
1. Not knowing how to do certain things in OS X. Not your fault that you didn't to begin with. However, learning the OS takes some effort, especially coming from Windows. There are plenty of free ways to do this on the Web, as well as books.
2. Problems with your iMac, hardware, software, or both. These are typically very difficult to diagnose without hands-on. Have you taken the computer to an Apple store or authorized reseller?
