Why use Zoho rather than Google Apps

Why use Zoho rather than Google Apps

Currently I use Google Apps (using my own domain name) for my mail / calendar /contacts.     This is all in sync with my mobile devices.   It all just seems to work and I'm comfortable with it.   There are only two users in this account, myself, being the primary user (and administrator) and another is a family member that is just has an email address (not really into computing or the internet).

Anyway, I'm not paying for Google Apps at the moment.   

What would be valid reasons to change over to the Zoho system of doing things?   With a second user on my account, does that mean I'd have to start paying?   Oh, btw, I'm not a business.
