I've been wanting to write a blog post about this transition for ages. Perhaps I should.

Here's a quick list:

* Cloud (files, contacts, photos, calendar): https://owncloud.org

* RSS Reader: http://selfoss.aditu.de/

* Bookmarks (ala pocket): https://www.wallabag.org/

* Email: http://www.iredmail.org/

* Chat/XMPP: http://prosody.im

* Git: http://gitolite.com/gitolite/index.html

* Blog: Blogophile static site generator (but wouldn't recommend anymore, Jekyll is better).

I keep my contacts and calendar on owncloud and sync to my Android with DavDroid https://davdroid.bitfire.at/what-is-davdroid

On my phone I installed CyanogenMod without Google apps but I recently got a one+ phone with CM installed by default (with Google apps). https://oneplus.net/
