The war between free email services is getting more interesting. Yahoo has rolled out email search, address auto-complete, and a few other enhancements to Yahoo! mail. Gmail already has a very useful search mechanism on archived mails, so this feature addition was expected of Yahoo. Now what will Hotmail do? Anyway great time for end users. Now one question creeps in my mind. Why would anyone want to pay money for email services, when you get all these great features for free?
