I have been following WINE since it was still very early in the development, and it is amazing how usable it compares to its early days.<p>Combined with PlayOnLinux, in some ways, it&#x27;s better than running Windows apps directly on Windows, as it can isolate one environment from others. (I can make the different WINE virtual drive to run Windows XP environment for one and 7 on another. It can even do 16, 32, and 64 bits, too -- real Windows can&#x27;t do 16 in 64, though these days it&#x27;s rare I encounter so much need for that.)
