iPad and iOS 4.0 - we wait, hopefully

The more I use my iPad and iPhone 4, the more I appreciate the improvements in the newer version of the operating system. It isn't really the multi-tasking, or the improved spell-checker, or the combined email Inbox, although all of these are desirable. The thing I really want, more than any of these other features, is the persistence between sessions so that, when I want to check my email when I'm halfway through catching up on Flipboard, I don't then have to start again from the beginning of the app.

iOS 4 is supposed to hit the iPad sometime in the autumn, but that's about all we know. Roll on autumn.
