Well,when we look at this question,I think we should look at the advantages of iPad 2 first.
1.a faster CPU and GPU.
It could let you run apps much smoothly and surely get better gaming experience.However,according to the users of original iPad,most of apps could run quickly,at least reaching their expects.However,a better GPU is a great point as many iPad users complain that the performance on the current one is too weak.
2.a sharper screen.
Although the resolution of iPad and iPad 2 are the same,1024*768 pixels.However,in the latter model,it could support 132ppi,meaning that you will have a more detailed display,especially when you’re enjoying those HD videos or high quality photos.
3.camera
In iPad 2,Apple finally brings camera function in.In fact,it’s not a new idea,but it’s new on iPad.The front camera could be used for Facetime,a video communication tool in iOS and the back camera could shoot 720p HD video in 30 frames/sec or make photos.It’s better than the original one that has no such functions.
4.Smaller size and lighter weight
iPad 2 has lost the belly and weight so that users could carry it more comfortable and convenient.
5.Support 1080p HD play
Compared to the previous one that only support 720p,iPad 2 is able to play 1080p HD video.Thanks the new GPU!
6.2 colours
Black and white are in the list,not like the old one that has only one colour.
7.HDMI output
iPad 2 now supports HDMI output with connecting with the specific cable costing US$39.With it,sharing something in your iPad 2 to others will be easy.That’s pretty nice!And you could try to play games,read articles,doing some work etc. on the bigger screen too.
8.3-axis gyroscope
It’s a new stuff in iPad 2.I thinks developers will know how to use it to create more interesting apps to attract potential customers.
That’s my two cents.Well,it may not be complete,but I think it could be your reference when you make decision-whether it’s worth buying it or not. Consumers are always smart,aren’t they?
