I feel soooo left behind..... still running Snow Leopard and have for that reason not moved to iCloud.

I can't seem to find what happens to my .mac or .me email on my iMac's "Mail" when I move to iCloud?

If I move to iCloud and not upgrade to Lion can I no longer get my .me mail on my iMac?

If I upgrade to Lion and then move to iCloud how does the "syncing" work? Do all the "mailboxes" for my .me account I set up on my iMac get synced to iCloud?
