If I understand correctly, MobileMe Mail will only work in the future under ICloud. For iCloud you need iOS 5 or Lion on an actual computer.
I have 4 Apple computers currently in use, I use mail on whatever computer I am on. Only one has Snow Leopard which can upgrade to Lion. One has Leopard and 2 have Tiger.
Does anyone know if at least one computer has the most updated OS that the information will show up on other computers?
I am not interested in an iPhone or iPad for email use since I require a full keyboard and tend to write lengthly emails.
