localStorage may be slow for read/write, but it's very easy to mitigate the problem by doing memory caching and delayed writting. Also storing file in localStorage is a bad idea. There are better way of caching file (offline storage, expire headers, etag, etc.)

localStorage has a lot of space for improvement, but I don't think they should stop to advocate it. It just feel like going backward.
