My arguments not to get MobileMe.
Sync My iPhone is always docked at home, so my contacts/calendars/... are always synced. My iPhone and MacBook Pro are never separated for more than a day, so synchronizing is not really important to me.
E-mail I now use a Gmail address which I'm perfectly happy with (IMAP). If the @Mac domain were still available, I probably would've gotten MobileMe right away, but I really dislike the Me.com domain name. (shallow, I know)
iDisk I already have a Premium Rapidshare account for 55/year which has a lot more storage than the iDisk. I use Speed Download for managing my up and downloads and that works seamlessly with Rapidshare.
Downside: other people I share files with have to have an RS account as well, otherwise they are limited. (not really my problem though)
Back to my Mac I heard it doesn't really work as advertised, so I guess this feature isn't worth it?
Photo sharing Facebook integrating with the new iLife '09 suite is another thing that convinced me not to get MobileMe. All my friends are on Facebook, so if I wanted to share an album, Facebook would be the way to go. (Heck, it even supports face tagging unlike MobileMe, right?)
Alright ... please counter these arguments - if you can - and try to convince me to get MobileMe.
For now, unless MobileMe is going to be sporting some cool new features in the future, I won't be subscribing.
