Why don't more apps sync progress over iCloud? Apple has such a great feature and very few apps take advantage of it. Cut the rope does it very nicely, play some levels on my iPhone go over to my iPad and the progress stays in sync.
I feel what you're saying ... The wierd part is that even small apps do not take use of this advantage ... they will setup their own cloud space on amazon with money and ask you to register and stuff but will not include same using iCloud
That's two bad iCloud could be so much more. They should start by cleaning up that API, adding Dropbox like file storage or at least sync PDFs via iBooks.
I hope Eddy cue lives up to the "mister fix it" image people have of him.
