I would love iOS to have widgets, but I don't think Apple will ever put them on the homescreens until they can figure out how to get them to work seemlessly. Everyone knows they're hit and miss in Android (don't refresh, lockup, etc...) which has been a constant complaint since the beginning, so Apple will never put that into their UI until it is perfected. I'm sure that's why they have them in their own screen. Kind of like a test I think. It would be great though. That's really the only thing I like about Android over iOS.
