The iPad comes in models ranging from 16GB to 64GB. All versions will have Wi-Fi, but there will be options with 3G as well. Pricing for the Wi-Fi-only models is $499, $599, and $699 for the 16GB, 32GB, and 64GB, respectively. 3G versions will be $130 more.
The top edge of the iPad houses a standard 3.5mm headphone jack; the bottom features Apple's standard 30-pin iPod connector port, which is used for charging the device and syncing with other computers. There are also three speaker ports on this edge.
The wireless functionality is a huge selling point for the iPad and many of the features depend on it. Using Facebook as an example, Jobs demonstrates that you'll get full-on Web browsing, rather than the mobile-optimized version found on the iPhone and iPod Touch.
Naturally, Apple wasn't going to let all those iPhone and iPod Touch apps go to waste. There was some scaling and tweaking required, but iPad owners can expect a store full of 140,000 apps to choose from (and counting).
One of Apple's main goals with the iPad is to take on the Kindle and other e-readers. Of course, it has a big advantage with the color screen, which increases the functionality of the reader and allows for unique browsing experiences, such as the Bookshelves view in Apple's new iBook store.
It's not for everyone, but one thing is for certain: Apple's step into the tablet space will not go unnoticed. Don't be surprised to see a slew of copycats cropping up over the coming months, or...dare we say it? Better and cheaper tablets from other manufacturers.
