Apple wants to get you hooked on MobileMe so that you will renew your subscription every year ($99 per year!). Ten years of that and you could have bought yourself a white MacBook instead.
At that price tag you can expect people to look for alternatives.
Let's take a look at what MobileMe actually does for you and how else it could be done:
You get an email address that stays synced between your mobile device, computer(s) and internet. Gmail does that too, for free. You can set up forwarders in the same way that you can for MobileMe. And if you're tight on cash one year you don't have to worry about losing all of your emails and contacts because you couldn't afford to renew.
You get an iDisk to store and share files. You can also use it as a web server to host your site.
For an online file storage and sync solution I much prefer Dropbox. It's free for the first 2GB, cross-platform, and you get not only public and private folders, but also folders that can be shared between just you and a friend. If you want more space you can purchase it. You can share public files as links, just like with iDisk. Actually I think Dropbox was first to have this feature. (Here's a
referral link for those who are interested)
Dropbox cannot be used to host websites though.
MobileMe calendar. This calendar syncs seamlessly between iCal and your iPhone calendar. Nice and easy for iPhone owners. Although I suspect Google's calendar could be used as a substitute. If anyone here is using Google calendar in such a way I would like to hear how it's working out for you.
MobileMe also automatically syncs your photos between your iPhone and iPhoto. So if you take a photo with your iPhone it is instantly backed up to the "cloud". This is a nice feature for people who don't connect their iPhones to their computers very often to sync. If you
do sync frequently though, it may not seem so important to you.
Back To My Mac is a MobileMe feature that enables remote access and screen sharing between two Macs running Leopard. So if you want to access your work computer from home, you can. This is a pretty cool feature, and if I had two Leopard Macs I would use it.
Here's a Life Hacker article on how you can accomplish this
without paying for the MobileMe service!
I hope that puts things in perspective for ya.
