Good point , I've had a few programs that I was happily using in Wine suddenly auto update themselves and start crashing all the time or cease working at all. For this reason I simply couldn't recommend using Wine to anyone who requires a particular program for their work (unless the developer specifically targets Wine as a supported platform , such as XMLSpy).

Also some games have DRM which does not work with Wine, so the only way to get it to work is to run a cracked version. Steam should fix that.
