K, I'm not sure I see what the issue is. The m in the address is just a temporary change and will eventually be removed. If you switch to the new homepage you can still type in www.yahoo.com and it will automatically re-direct you to m.www.yahoo.com, so there is no extra typing on your behalf. So, I'm afraid I really don't see the problem - could you elaborate why this is such an issue for you?
