How about this for more positive yet realistic phrasing: "Of the apps we have tested with Wine, about half work well enough to try, and of those, half work well enough to use routinely. In particular, Photoshop CS2, World of Warcraft, Firefox 2, and many small apps run very well. .NET based apps and Photoshop CS3 are not yet supported."
That just sounds more confusing...
Is "percent of apps we tested" a formal release criterion for Wine 1.0 ? If not, the stats seem irrelevant as far as this release is concerned. If yes, why release with so many apps not working well ?
If you want to set realistic expectations - list major supported apps along with a link to appdb called "Will my app work under WINE?". Then the users will have a realistic expectation of whether their individual apps work. Setting realistic expectations with a rather low percentage number just means a lot of people won't even bother trying.
