Net Applications: Chrome At 1% Marketshare

But since people don't pay for browsers, it's not a terribly relevant metric. The issue is how to turn browsers into money. For a decade, we've heard Explorer will let MSFT dominate online services, photo finishing, travel, search, I could go on. Now GOOG and MSFT are arguing over whether Chrome is best for (free) online apps. But until we know why Google Docs is a meaningful ad medium (dubious), or why people would pay for it (because at $3 a month it would be cheaper than buying Office, which is the usual ASP reason for being) then it's hard to get real excited about this.

Net Applications is not a reliable source of metrics.
