I had a project that was pretty much a perfect fit for the app cache:

    - 100% static
    - reasonable dataset size
    - amenable url space (a few static files, then a large url
      space that could fall back to serving out the index.html 
      file)

Despite this, the appcache just never worked reliably. It was a crapshoot whether it would actually work offline for any given user, I had to be careful not to permanently cache the appcache itself, and it was just generally inflexible and unpleasant.
