Two Google items I noticed while browing the Official Google Blog.
http://google.com/m takes you to Google’s web transcoder that transforms non-mobile friendly web pages into mobile device friendly ones according to the blog item Viewing the web through a mobile lens.
The blog item titled Simplicity and power talks about recent enhancements to the Google Page Creator (as in web page). One of the new features is called Pages for mobile and is described like this: This feature has an awesome power-to-complexity ratio: Now, every Google Page Creator site automatically has a mobile edition. So when people visit your site from their mobile browser, they will see it optimized for their particular phone.
