We are at a stage where games built for Windows actually run better on Linux so this argument will probably not be relevant for too long anymore.
And computers aren't just for gaming. Some people actually work with their computers. Let me know when photoshop or autocad run smoothly on Linux.
If autocad or photoshop don’t work it’s not because Linux can’t handle it, it’s because the authors of those programs don’t want you to. It’s DRM, every time; not some limitation on what wine can do.
Otherwise it has been running really well.
