If you haven't checked out Parse yet, take 5 minutes and go through their quick start guide. (Documentation is written exceptionally well)

The PFObject class alone allows me to do work in minutes that used to take hours with server setup. Also, great classes like this UITableViewController subclass are always being released.

The only thing better than this platform, is the team running it. They are taking the time to do the little things and build a great product. They answer each email they receive, they genuinely listen to user feedback, and they are always looking for new ways push the platform forward.

I am with @Skroob on this one. This is one product I look forward to using the most in 2012.

PS- If you are worried data only on a remote server, you can always serialize the object and store it in a flat file or mirror it over to a NSManagedObject and store it in CoreData.
