Email does not work!

iCloud is BRUTAL! Email does not work or at best works intermittently on my Mac's. I have iMac and MBA. Neither are synced correctly, both are missing messages in MAIL app.

Some messages make it to my phone (android thank god) but usually I have LogIn error there too!

Apple, figure this out with a BETA before you roll it out to all of us and make us switch from MobileMe!
