Do we still need to install office suite?

Recently had come across Gliffy.com, a web based diagram drawing tool. Although still in its beta, it is already very impressive.

For now, it is not as good as MS Visio. However, it is much better than drawing diagram with MS Word. It can become a real threat to MS Visio and other diagram drawing tools if the collection of icons can be enriched.

After using Gliffy, I am thinking whether we will still need a Office Suite if we had an Internet connection. Then I go google for other web based office suite and I found this blog entry.

This article on Feb 2006 had list the best of breed web office tools. And as we know, Google had lauch Google Calandar and Google Spreadsheets, and buy Writely (a web based word proccessor). It will not be surprise if Google release a Web Office Suite as what Zoho.com is doing now.

So do we still need to install Office Suite?
