I guess I am glad the pay version of MobileMe is going away. We had two of these accounts and in this day of lots of resources available at no cost, $100 per account was pretty pricey.
Still, beyond what is known about the music, email, and calendars, what will happen to other MobileMe services. Here is a “best guess” from MacWorld.
I do wonder about iWeb and photo sharing – I liked how the web construction software worked, but the service through MobileMe seemed limited. I played with a small site, but pretty much moved everything elsewhere when I got a little more serious. If you ever attracted much interest to your site, you would likely exceed your base rate and have to pay for more capacity. I understand that the iWeb software could be used to build a site anywhere, but I never bothered after moving on to other services and software. Apple seemed only mildly interested in the participatory capabilities of the web. I do think the integrated nature (Mac) and ease of use of iWeb would be helpful to some wanting to maintain a basic web presence. Maybe the $25 for the music service allowing other than Apple store music will offer some of these other services as well.
