Is the Hebrew text of Maimonides' Moreh HaNevuchim available for free online? (In text form rather than Pdf).
Hebrew: Ibn Tibon, Schwartz, and Kapach: http://mobile.tora.ws/
English (Friedlander) http://www.sacred-texts.com/jud/gfp/
Ibn Tibon and Friedlander in parallel: http://www.sefaria.org/Guide_for_the_Perplexed
If you're looking to pick a single one for Hebrew I would personally go with Kapach, but that's completely personal opinion with nothing to actually back it up. My reasoning is simply that Kapach is perhaps the greatest Rambam scholar since Rambam himself. He dedicated his life to studying the Rambam, and his knowledge of Arabic and Judeo-Arabic was excellent.
