I don’t understand how Microsoft continues to retain its position as software leader when there are so many competing free online resources available.

I am a big fan of Google Docs and its competitor Zoho. Lifehacker provides a good comparison of the features provided y both.

And there’s also Open Office, an open-source program which I believe is restricted to your desktop and not available via the internet (last time I used it was in 2005).

Yahoo! just acquired Zimbra — which is more of a training or webinar type service to compete with Zoho Chat and Meeting

Now that I’ve switched from PC to Mac, I’ve been using Google Docs and Zoho (I really do need to commit to one) exclusively.

What do you use?
