Princeton University's Office of Information Technology is now suggesting that the iPad's DHCP lease renewal problem may be related to the iPad's screen being locked, either manually or automatically. The best workaround seems to be to disable automatic screen locking and avoid locking the screen manually; the downside to this is of course reduced battery life. Other (but worse) possibilities include turning off Wi-Fi or the entire iPad at the end of each session.follow link
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
