Apple iPad

Hardware Industrial design The first thing you notice about the iPad is, well, you don't really notice it. In many ways, there is just not much here -- design wise -- to comment on. The bulk of its surface is taken up by a 9.7-inch, 1024 x 768, capacitive, multitouch LED-backlit display surrounded by a glossy gpad black bezel that some will say is too wide but, in practice, is an important design consideration that prevents the touchscreen from being inadvertently activated when handled. There's only Apple's signature "home" button to interact with, and the back of the device is a dutifully simple gpad 7 piece of curved aluminum. Like most Apple products, it's a beauty to behold, but it's not exactly notable for design flourishes; simply put, it's good looking but not terribly exciting. But if the design of the iPad is an exercise in restraint, it only serves to reinforce how formidable this technology connection kit feels once it's in your hands. The device has some heft, weighing in at 1.5 pounds, but is still comfortable to hang onto at most angles. Considering the computing power of the tablet, a thickness that tops out at half an inch is pretty impressive, too. But how does it feel in your hands? Well, that matte aluminum on the back surprisingly ipad dock communicates warmth (though we don't recommend resting this on any bare flesh on a cold morning), and the rest of the design gets out of the way and lets you concentrate on what is really most important: that screen. And that's kind of the point, isn't it? The iPad does house a few other components you should be aware of: a volume ipad keyboards rocker and screen position lock (which forces the device to remain in landscape or portrait mode) on the upper right hand side, a power / sleep button and headphone jack on either side of its top edge, and Apple's famous 30-pin dock connector alongside a single thin speaker on the bottom of the unit. There is nothing outwardly notable about the buttons or layout on the iPad -- if you've used an iPod touch or iPhone, you'll find yourself right at home... and that's exactly how Apple wants it. As far as ergonomics are concerned, the standard seated-with-iPad-in-lap move is a completely comfortable experience, but there are definitely use cases where handling a flat slab becomes a pain. For instance, single finger typing becomes a bit of a game of hunt-and-peck, and that's the situation you find yourself in if you're ever standing with the iPad or holding the device with your other hand. We mentioned tha,ipad keyboard t iPad has some weight to it, and while it's comfortable to hold, it is considerably more of a handful than an iPhone. You'll feel that weight in your arms after extended period of keeping it aloft. Apple promo videos like to show their users happily grabbing the iPad and swinging their legs up onto a table -- Fonz style -- but if you're like us, most of your ipad charger heavy text entry is done while seated at a standard table or desk, which means that unless you have a dock you're going to be typing on the iPad as a flat surface. The thing is, we actually found the flat-typing experience to be pretty good; it takes a little getting used to, but it's not totally bizarre either. In fact, we'd say it's a much more enjoyable experience than single-hand typing. Still, just as with the iPhone, there ipad charger is a learning curve here that may diminish some hit-and-run shoppers' interest. Internals As you probably know by now, the iPad packs Apple's custom, PA Semi-designed 1GHz A4 system-on-a-chip -- a single Cortex A8 core coupled with a PowerVR SGX GPU. RAM on the iPad hasn't been revealed, but we suspect there's 512MB (at least) inside ipad stylus here -- we'll know more once iFixit or someone else puts the pad under the knife. Also onboard is 802.11a/b/g/n WiFi, Bluetooth 2.1, a digital compass, an accelerometer, microphone, and ambient light sensor. The 3G model that ships at the end of the month will add UMTS / HSDPA data along with an AGPS chip. You can purchase the device in capacities of 16GB, 32GB, or 64GB. We had the 64GB version for this review. In our testing, the A4 SOC seemed to deal with whatever we threw at it handily. From opening and rendering webpages to playing the most graphically intensive games (including scaled iPhone versions, of course), it didn't miss ipad keyboards a beat. The photo app was iphone 4 case particularly impressive, allowing for fast scrolling through high resolution pictures without a hiccup, and handling rotation and zooming with no resistance or hesitation. Applications themselves opened quickly -- not instantly. Of course, as many detractors have noted (Engadget included), there's no true multitasking here, so seeing a system with this much power perform admirably one app at a time wasn't a huge surprise, especially since we'd experienced the same thing on an earlier version at the January event (more on this in a moment ipad keyboard case ). Still, it seems like the A4 has power to spare, and that's a good thing if the third party apps we used on the iPad were any indication of where things are headed -- more graphically intensive and packing far more functionality. The battery -- a 25-watt-hour lithium-polymer (non-removable of course) -- held up surprisingly well in our testing. More on that in the battery section down below.
