Well the long wait was over and I've been goofing around with my newly updated iPad now running iOS 4.2.1. So far... so good!
One question that does strike me as intriguing right off the bat relates to multi-tasking. When you run an App and then hit the home button the App remains open and running. When I go to another App, same thing happens. Is there anyway to leave an App without it being sent to the multitasking bar? Meaning, can I use my calculator and then close it directly rather than performing extra steps to close it out of multi-tasking?
