I'm guessing all of the delays their having with the push notification is due to all of the problems their having with mobile me. I'm sure its the same design. I don't think they'll ever be able to get it rock solid - and even if they do - all it will take is one glitch and all of our programs that will rely on it will fail at the same time. it will be a 100% failure rate. Much like when blackberry has a problem. Apple seems to not understand this type of functionality. Plus i think its adding such a complicated layer that is unnecessary. i would rather have lower battery life (and my guess is its not going to be that much lower) but have it function as it should - apple should allow background demons. I think their going to fail with the way their going to implement it. How will Messenger applications work? You log off - get an IM - have to close down what your working on - open the messenger app to respond the go back to what you were working on. It wont work. What do yall think?
