Should You Change To The iPad 2?
Regarding the physical size, the iPad 2 is a lot smaller in size compared to the original iPad. The iPad 2's screen size continues to be the same at a decent 9.7 inches; nevertheless, the thickness of this newer model has been reduced by a third of the original size, which of course is a good thing. At 600 grams, the iPad 2 is lighter than the original iPad. That's much lighter. These modifications are perceptible as I observed by holding the iPad and iPad 2. Don't think a skinnier and less heavy design means the performance is affected, because boy oh boy would you be wrong...
The new iPad is in fact a lot quicker than the original. The graphics processor is bragged by Apple to be 9 times faster than the original iPad. If that is true, it is a huge jump forward. Gaming requirements and the introduction of cameras is why this had to happen. An A5 chip means that Apple also now has a processor that is a great deal speedier. The newly released iPad's A5 dual core processor is what makes it faster than the last model. I surely noted it was zippier, even with a lot of programs running in the background. I've as well taken a look at both the iPad and iPad 2 side by side and I can definitely say you observe things, such as web pages and video, loading quicker.
The iPad 2 now comes with two cameras. The first camera is on the front side and the other is on the rear. This is a major move as the first iPad did not have camera at all and this may be important to you. A more or less better capability of one of the cameras is the ability to shoot in 720p HD. The iPad 2 has now added FaceTime and Photobooth, providing you the ability to video call and snap all sorts of photographs. The front camera positions you face-to-face when video calling when using FaceTime whereas the iPad's back camera displays your surroundings.

If you are able to afford it and wish the new quicker processing times then changing from the first iPad to iPad 2 probably makes sense. Even though the upgrades are an improvement, it's nothing significant, apart from perhaps the camera which is a brand new addition.
