I have been a Yahoo! email and IM user since, well, forever. After enduring almost 3 months of delays in email delivery, slow GUI performance, and timeouts, I have to look elsewhere. My decision was confirmed after seeing the Yahoo exec's quoted comments to employees that Yahoo! mail customers would have to have their privates kicked in order to leave.
Farewell Yahoo! Hello Google!
Oh, and for those that want to do this...Google has a feature under Settings/Accounts/Check mail from other acounts that will pull in all mail from your Yahoo inbox. It does not support Yahoo IMAP folders. What I am doing is getting the inbox first, then moving each Yahoo folder one by one into the Yahoo inbox, and then changing the label that Google uses to mark the message.
Contacts can be imported by exporting them as vcards from Yahoo.
