As the US and EU regulators bear down on Google we're already seeing changes in the marketplace where the Googlers currently have the lead. Yahoo! is catching up to Google with several innovations in its email client. Unlimited Storage, a built in RSS reader (not separate and clunky with a just-added search function), push email for the iPhone, better contacts that syncs with the iPhone, built in SMS, and drag and drop functionality are all unique to Yahoo! mail, at least for the moment. There's no doubt that GMail will catch-up, but that's exactly what competition is meant to do, force competitors to improve or perish. Read more about it at LifeHacker.
