How to use windows appications in Linux (Wine for linux)

One biggest thing that stopped me from using linux as operating system was how I would use my favourite applications from windows !! Well in the current scenario, a solution to this comes in form of "Wine" software for linux wherein you can run applications of windows in Linux environment. The advantage linux (ubuntu in my case) gives is that it take quarter the time to boot up and net is much much faster than windows. Plus its entirely free to use with great interface.
