Probably not. Your third-generation iPad is the same powerful, Retina-display-sporting iPad it was a week ago. Sure, the fourth-generation iPad boasts a faster processor and further improved Wi-Fi speeds. Remember, though, your third-generation iPad is no slouch--in fact, it's downright speedy.

Predicting Apple's plans and being right 100 percent of the time is impossible, but this week's fourth-generation iPad release is most likely an indicator that Apple is shifting the tablet's release cycle from March to October. It can't hurt that an October release pushes the new product out in time for the holiday season. In other words, you probably needn't fear that yet another new iPad will show up in March of next year; we'll probably have to wait until October 2013 for the fifth-generation iPad to appear.

Nope! Your iPhone and iPod touch run iPhone apps. The iPad mini runs iPad apps. Yes, when Apple first unveiled the iPad, people called it a big iPod touch, and the iPad mini is a smaller big iPod touch. But they're different devices, geared toward different uses.
