Not trying to start a fight but what is wrong with hotmail, yahoo etc????
There is absolutely nothing wrong with yahoo or hotmail. They use a different protocol (pop3) than gmail (imap). The difference is that imap is a "sync" with email server. Pop3 simply downloads and uploads mail to and from the server. For some reason, people think gmail is "optimized" in Android. This is not true. Android simply signs in your gmail automatically when you first turn on your phone. Because of this ease of signing in, it is assumed that something is "optimized". Again, it is not. the gmail app and the htc mail app handle imap exactly the same.
