Internet Explorer market share down to 70%

For the first time in 8 yrs, Microsoft Internet Explorer market share is down to 70%. What does this mean? I don't believe that this is an indication of greater popularity of Mozilla, Opera, Safari etc. But this is due to more and more web-based applications that are now accessible through many non-IE browsers. Users are moving to Web-based Office, Social networking, Collaboration and maintaining their personal/professional content on the web. Any browser that supports the delivery and manipulation of this content will see an increase in market share. On the flip side, browsers that do not support direct integration will see a decrease in market share as is the case with IE.
