@Ryan - Yep, all browsers are now reflecting the change. Mobile devices are next and I'm seeing tests on iOS and Android showing sporadically.
@Bryan - It's big. Huge. Until now it was possible to hide SEO deficiencies with a strong Local/PPC strategy. Now, that's more challenging as the algorithm driving Local results is tied in directly with organic SEO.
@alex - "I can’t stress enough how important it is to work on your customer reviews." No question. Reviews were often difficult to find in the old search as they only showed up in Places. Now, you can't really miss them. Also, GREAT observation on conversions. People use Google as the Yellow Pages now and having that important piece of data available without having to click may hurt traffic, increase conversion rates, and decrease "bad bounces" that occur when people click through just to get a phone number.
