I'm using Zoho only for personal usage. But still, I don't get it. What are the limitations of a free account? I had a look on this list:

http://www.zoho.com/pricing.html

and thought I might find a comparison table. But it only says "free for personal use". Well, that's nice. I see that there is "Zoho Business" for example, and of course it's logic that this has a price. But I don't understand, for example, if things like "Zoho Docs" or "Zoho Wiki" are free for personal use or not. Are these business applications that I don't have as a personal user? Or are these upgrades to the business prices?

I don't get it. It's confusing. The first time I entered the Zoho website, I even didn't understand what this is all about. It's so random on Zoho's homepage, looked to me rather like a company that provides frameworks for programmers or software business solutions, such as APIs. For a first time visitor of Zoho's website, it's very difficult to grasp what Zoho is actually about in the first place. When I signed up, I even wasn't sure if I did a mistake now or not, if this is some hidden pricing thing I signed up for. Because I just couldn't get any reasonable overview on Zoho's purpose and for whom it is really free and for whom not. "Personal use" can mean anything. What's personal in this context? And when does Zoho consider the use being business usage? For example, is business usage already given when my colleague sends me an email? It's not defined or explained on Zoho's website. And even this link doesn't make it clear:

It would be nice to have a table where users can see what the differences are between the personal and the business use. For example, I read somewhere on the forum, that there are limitations of how many emails a business user can send, according to his pricing plan. Now this raises the question to me: And what are the limits for personal users? What are the limits in general and for each of those applications when you're a personal user? There is absolutely no information about this on Zoho's website. Or did I overlook something?
