I've had these services since I had a free trial with my iMac quite a few years ago. I found homepage genuinely useful for sharing files. It was possible to create a sharing page that was password protected and quite secure.
It's a shame that they're killing the service off, rather than just incrementally improving it.
This whole MobileMe thing is infuriating. One day, without warning, I suddenly realised that I was sending email from my address @me.com instead of @mac.com. That was the first I heard of it.
Their email system no longer supports aliases in the transparent way it used to, and there are a lot of other major changes too.
Finally, I find the MobileMe synchronization service for iPhone pretty shockingly bad. I set it up, and my entire contacts directory disappears when it attempts to synch.
I can't seem to find out how to get it back to normal.
Frankly, I think I will be changing over to google aps
