Google Spreadsheets are catching up on Zoho.

They are definitely getting there, but Google kind of has a different approach on how they are rolling out features. They tend to find ways to keep the interface clean and managing documents simple, and I don’t think they’ll release any features that would compromise that. They tuck away the more advanced features rather nicely so that they won’t confuse the casual users. Pretty smart if you ask me.
