Apple iPad: Everything You Need to Know

From the realm of sci-fi to Steve Jobs' stage: The iPad is official. What is it? What can it do? How does it work? Here's everything you need to know about Apple's newest creation, all in one place.
It's almost impossible to overstate the buzz leading up to this device. Immediately after the death of the Newton, rumors began trickling out about a followup from Apple; in the last five years, speculation and scraps of evidence about an Apple tablet have been a fixture in the tech media; in the last year, the rumors were unavoidable. Today, Apple's tablet has finally arrived, and we've got the full rundown—from specs, features, content and price to what it's like to actually use one • Size and shape: The screen's aspect ratio makes it seem a bit squat, but this is intended to be a bi-directional tabl—err, Pad. The bezel is a little fat, but otherwise, this thing is basically a clean slab of pure display. It's just .5 inches thick, which is a hair thicker than the iPhone 3GS, and measures 9.56 x 7.47 inches. Final weigh-in is 1.5 pounds without 3G, and 1.6 with. Says Mark, who's actually held one:

Imagine, if you will, a super light unibody MacBook Pro that's smaller, thinner and way, way, way lighter. Or, from a slightly different perspective, think about a bigger iPhone that's been built with unibody construction

The guts: It's a half-inch thick—just a hair thicker than the iPhone, for reference—and weighs 1.5 pounds. It's powered by a 1GHz Apple ARM A4 chip, and has 16GB, 32GB or 64GB of flash storage. From the looks of it, Apple finally got some use out of that PA Semi purchase, and built their own mobile processor, but that's no totally clear yet. It's also loaded with 802.11 n Wi-Fi, Bluetooth 2.1 + EDR, a 30-pin iPod connector, a speaker, a microphone, an accelerometer and a compass. Video output runs through and iPhone-type composite adapter at up to 576p and through a dock-to-VGA adapter at up to 1024 x 768. No HDMI, no DVI—not even a Mini DisplayPort.
3G is optional, and costs more, not less. Along with 3G, the upgraded models include A-GPS. (More on this below)
Oh, and there isn't a rear-facing camera, nor is there a front-facing camera. This tablet is totally camera-less, which seems a bit odd. The battery: Apple's making some bold claims about battery life: ten hours for constant use, with a one-month standby rating. Ten hours of constant use includes video viewing, so you could conceivable watch about six feature films before this thing dies
How you hold it: You can hold it two different ways, and the software will adapt to both. Portrait mode seems like the primay mode, a la the iPhone while landscape mode—better for movies and perhaps magazine content—is a secondary mode. The Apple decal is oriented for portrait mode, so basically, just get ready for a whole bunch of HEY IT'S A GIANT IPHONE!! jokes.

Connectivity

Some models have Wi-Fi exclusively, while some have 3G as well. It's with AT&T, and costs either $15 a month for 250MB of data, or $30 for unlimited data. With the plan, you get access to AT&T's Wi-Fi hotspots as well. Best of all, it's a prepaid service—no contract. You can activate it from the iPad any time, and cancel whenever you want. This sounds like a fantastic deal, until you consider how it's probably going to brutalize AT&T's already terrible 3G coverage.
The iPad itself is unlocked, so you can conceivably use it with any Micro SIM card . But what the hell is a Micro SIM card? For one, it's not the same kind of SIM that's in your iPhone, so don't expect to just pop that in and surf for free. It's a totally different standard, and the iPad's the only device that uses it right now. Even if, say, T-Mobile released a Micro SIM card, the iPad can't connect to its 1700MHz 3G network
