I don't think I saw OpenStreetMaps in the lists provided by various people in this thread. I rely on GPS a lot, and having a local one would help greatly (preferably on phone, but still).
Also, OpenLibrary, AniDB / Anilist / Anime-Planet / GoodReads / IMDB / jeuxvideo.com / Last.fm / LibraryThing / MangaUpdates / MyAnimeList / MyDramaList / NovelUpdates / Shikimori / TheTVDB / WLNUpdates (databases of various entertainment stuff).
Then I can look in the GPS where to find them.
Even without GPS, I imagine osm would still prove invaluable in saving lives during a disaster.
I wish there was a simple, portable, plug-and-play solution for downloading and viewing maps on Linux/Desktop computers.
