"No, the question is: who doesn't understand whom?"
Apparently you don't. If you have MobileMe (which you would have paid for), you would have sync services, and those continue until June of next year. If you upgrade to iCloud (which is a choice) then you need (at this moment) LIon and iOS5. iOS5 is free, Lion is a measly $30. If you don't want Lion, right now you pay nothing more and you still have full sync with MobileMe, it is only after you upgrade to iCloud certain things go away. So the answer is simple, don't upgrade your MobileMe service and nothing, absolutely nothing changes. Sure in June some decisions need to be made, but in the computer world eight months equals several years for other industries, by then they could have it working better for Snow Leopard, but it still would not be free, why should it be? MobileMe was never free. $100 a year is many fold more costly than a one time upgrade for $30. So if you want iCloud for free then yes, you need to buy Lion. If you are a MobileMe customer with devices that don't support Lion or don't want to pay more, then don't upgrade right now. Very simple. Who knows what will be available eight months from now.
As in the past, as it is for the present... Patience IS a virtue.
