I don't like my imac?

I'm guessing you were a Windows user like myself before getting an iMac. I got an iMac late last year, and yes, it's quite a big change from Windows, but if you give it chance, it is way more intuitive and fun than Windows. As for right-click, you can customise that in the settings where there is a section labelled 'mouse', and if you don't like the mouse that comes with the iMac, which I presume you are using, you can buy one from another company (most mice work with both Windows and Mac). The sound thing sounds (no pun intended lol) a bit unusual, and you should speak to Apple or the store it was bought from about it. . Really, if you give it a try and keep an open mind you may end up loving it :)
