1. A web-based email client that's as good as gmail or fastmail, but open source, and runs on my servers. 2a. Document/file storage as good as Google Drive/Docs, that is open source and runs on my servers. Corresponding mobile app required. 2b. Open source cloud (a la ownCloud) with a better user interface and more features on both web and mobile (i.e.: viable as a Google drive replacement) 3. A mobile operating system that focuses on security and isn't too information-leaky. 4. A very nice android tablet replacement for stock headunits in cars. The key is that it should be easy to install and configure. One can create this now using torque, a bluetooth OBDII adapter, and tasker to act like a genuine headunit, but requires lots of configuration/setup.
