Yahoo! introduces Mail, Messenger and Search on Google's Android platform
I don't know many Android users who would be interested in switching to Yahoo!, especially when Google's service is so convenient on Android phones, but at least you have the option now. Lifehacker reports that intregration with the OS is actually pretty good, too: Yahoo! Mail can access your phone's address book, for example. The apps have push notifications and the ability to download attachments, too.
