I really hope us Mobile Me Subscribers get iCloud for free for the rest of our subscription. We pay $100.00 for services that I hear will be free in the future so I think we are entitled to something.
I'm currently on a trial for Mobileme and like the service, but if the price doesn't drop after Monday then I'll just stick with Gmail. I seriously doubt that iCloud would be free for current subscribers. I see Apple doing exactly what they did with Mobileme, free trial then charge for the service.
