Yes, it is better to check for specific features/problems than to check for a version number. Sometimes it's Really Hard to check for features/problems. Really Really Hard. Sometimes it is way more efficient to test for a version number than a specific feature/problem. I don't have any problem with that. If the version test is discovered to be insufficient, to resolve that insufficiency the test must be improved. There are times I still do OS-version checks to >make assumptions< about, for example, file system layout or startup script methods. Is this inelegant? Yes. Have I received any bug reports about it? No. Software isn't finished until the last user is dead. Evolution happens. Some "issues" are more significant than others.
