Hi
POL make installation easier, by configure the Wine Prefix not to have speeder launch but to have something usably.
Some times this one increase performance, but not always.
You don't need to remove Wine, POL use the system version prior to it's own version.
For some application we use a specific version of wine because of regression in wine.
PlayOnLinux will install all application into it's folder (~/.PlayOnLinux) and in a separate prefix (so there is no conflict between 2 or more apps. So except if you need disk space, you don't have any reason to remove wine folder's.
