iPad, 2010
And now the tablet is finally here. It's called an iPad, and it's half an inch thick, weighs 1.5 pounds and features a 9.7 inch display. As Steve Jobs says in the presentation above, the device has a 10-hour battery life, so you'll be able to use all the 3rd-party apps, games, video and online newspapers you want. The Wi-Fi iPad begins at $499 while the 3G version begins at $629.
