Well my friend, I think you did not look much for that information but there is the answer:
Odoo community is free to use and include about 80% of the content of Odoo enterprise.
Most new feature come in the Enterprise and they are put back in Community a few years latter.
Bigest difference for me is the fact that Enterprise can be upgrade to new version of Odoo (as long as you use only included module) while upgrading the community version is much more complicated.
If you install a community version, you will see in the moduie manager all the Enterprise specific modules that you can not install so you'll see quickly if you need it or not.
As per version 10.0 enterprise only module are: the mobility interface, the quality control, plant floor dashboard , worker center planning, barcode interface, and a few more.
