What do you want in os 4 iPad?
Based on my 2 days with the 3G iPad, the os 4 update will be huge in terms of making the iPad more like mini and very cool laptop.
Things I want to see in os 4 (not due for iPad until fall, apparently) are:
1) true multiple tasking (not a suspended state like the iPhone implementation) - iPad apps need to be able to truly function in the background
2) better file management - so I can open an excel file on the iPad, use it and e mailnback to a work colleague
3) better way to print
