I wasn't expecting much from the iOS 4 update. All I really wanted was smooth multi tasking and folders. While multitasking still needs to be worked out by more app updates, the folders UI is just horrible. I don't understand why do we need to have a lag when we open each folder. Not to mention that I cant switch between folders but have to go back to the main screen. The worst issue however is the lag when I open each folder. It is one tenth of a second but very annoying. If I really wanted a laggy tablet I should have gone for toshiba.
