Once Google feels comfortable enough with Docs that they put a little link to it on Google.com below the search box (like they did with Chrome for example), what do you think that percentage will be after a few months?
How many ways has MS encouraged upgrading to IE7, yet STILL 50% of salesforce.com users are using IE6. From 2001. For them (or the people with the authority to upgrade), the browser just simply isn't broken enough to warrant the pain of upgrading.
Exactly how much does MS-Office have to suck before people shift to Google Docs? A lot more than it does now.
Do you have data to back this up? My anecdotal experience with every person I know from my grandma to my niece to my girlfriend suggests exactly the opposite behavior.
The rest of the world clicks on links and uses/buys things just because they are there, and some smaller subset of people do it to solve a problem. ;-)
One could argue that MS Office 'sucks' just by costing more than GDocs which is free. If Google wasn't so opaque about what their plan for GDocs is... maybe they should go at it more whole-heartedly and promote it and then see what happens.
What I meant was that the valley tends to discard something as being yesterdays news that hasn't even hit the opinion leaders yet. Google docs is an example of this.
