Hmmmm, you still have to pay to get the big storage with Yahoo and Hotmail, so I'm afraid it will probably be too little, too late for them. Why pay for 2 GB storage, when Gmail will provide 1 GB for free? Who will really _need_ that extra GB?
My Yahoo account has been my primary email address since 1996, but if Gmail is all it appears to be (and I can ever get an account

) I will switch over without too much grief.
PS - In the meantime, Hotmail is making yahoo look cheap with it's "measly" 100MB mailbox, lol (I never thought I'd see the day I said that!)
