Why Google Docs will beat Zoho

Richard MacManus at Read/WriteWeb points out that Google Docs is the clear leader in the web office market.  He points to a Compete graph showing Google Docs as the clear leader.

Now it's time for me to state the obvious.  Here are reasons Google will win the online office applications battle:

• Google is already winning the battle.  Google Docs is well-integrated into other Google tools like Blogger.  A "killer feature" for Google Apps that receives much press is that it's so easy to collaborate.  It's possible to edit a document simultaneously - there's nothing quite like watching a document change in front of your eyes eve though the person editing it may be halfway around the world.
• Zoho gets a lot of press.  I wouldn't be surprised if Microsoft ends up buying them.  Probably a great app, but I'll stick with my loyalties to Google.  Even if Zoho might be a bit better, it doesn't matter because Google will be better in the long-run.  To date, I think Zoho's main advantage is the Powerpoint-like app, but I'm not really creating online presentations just yet.
• Yahoo owns Zimbra, but what have they done for me lately.
• Microsoft.... online?  Live what?  I just don't get the MSFT "live" concept.  Perhaps the only thing that would make sense for Microsoft is a 100% integrated online/offline app, but then again this makes no sense because of redundancy.  Or they could buy Yahoo and Zoho.
• What's ThinkFree?  At the very least, it's nice that they're not charging people for their thoughts :)

Finally, not that the Compete graph matches almost perfectly with buzz on the applications (courtesy of Google Trends).
