Is there any free/paid Windows emulator for Mac OS X? I am new to Mac and I am looking for a Windows emulator for Mac OS X. I want to use an application which is not available for Mac.
Please recommend the strengths and weaknesses (including cost) of the various options available.
Wine
You could try Wine and use the  Winebottler frontend for installing common Windows software.
With Wine isn't 100% compatible with all windows programs, so consider yourself lucky if all your applications work.
Virtualbox
Virtualbox is a PC virtualization software. You'll need to install Windows as a &quot;Guest operating system&quot;, which requires a Windows license.
Virtualbox is compatible with all Windows software, but has limited support for hardware 3D acceleration.
Boot Camp
For 3D games you'll need to use Boot Camp.
