I (really) wonder how many of these 10 million share my use case - I haven't used my hotmail email since gmail came out. But it is still active as I use it to 'try out' all these MS services when they come out. The day Outlook.com was released, I quickly logged in, checked it out, shared the news with some friends, logged out. Haven't logged back in since then (and don't plan to)
