The iPad 3rd generation represents the biggest upgrade to the iPad since the original model was introduced by Apple in 2010, with a faster processor and a new high-definition display leading the list of improvements over the iPad 2.


2,048 x 1,536 "Retina Display"
4G LTE support with the ability to be a Wi-Fi hotspot
5 MP Back-facing iSight 1080p Camera
Support for 1080p video playback
Voice dictation
1 GB RAM for applications (up from 512 MB)

1:The first thing that stands out about the new iPad is the improved display, which features a resolution with four times the detail as the original iPad and the iPad 2.
The enhanced display also means the iPad 3 will support 1080p video, which is a nice upgrade from the iPad 2's 720p video.
And while the iPad 2 doesn't support 1080p video, it does support 720p, which means you won't be hurting too much in the video playback department.

2:Equipped with a new chipset that includes a quad-core graphics processor, the new iPad will also be able to dish out these graphics at an increased rate, so we won't just be looking at stunning graphics, we'll be living in amazing new worlds.

3:Let's not forget about 4G LTE compatibility. The iPad can be a great home device, which makes the Wi-Fi-only versions so attractive, but the addition of 4G is a big boost for those who use the iPad while on the go. 4G can download at speeds three times faster than 3G, hitting the 10-12 Mbps range. That's easily enough to stream a high definition video and even act as a hotspot to another device browsing the web.

But but but .. There's one reason why 4G doesn't take the new iPad over-the-top: it's just too expensive. Sure, you can stream that high-definition movie from Netflix, but if you want to watch Netflix videos on a regular basis, you'll either want to plug in to Wi-Fi or expect a rather large bill.
