Should I upgrade to iPad 2?
For the current iOS, the hardware requirements are fine with iPad 1, but we will be getting iOS 5 soon and surely it will be developed considering iPad 2. iPad 2 has better hardware resources, cameras and is thinner and lighter than the predecessor.
Its now about a week that I am using iPad 2 and I feel its worth the upgrade. It works much faster, has a camera, good if you are a blogger, click and do a post.
I also got a bluetooth keyboard which is good when I need to write down notes and I am doing this post using my iPad.
My suggestion to people who are in a fix to decide if they are using an iPad 1 and want to go for iPad 2, then I would say that it will depend on how you use your iPad. If you use applications which need more hardware resources, then its worth or you can wait till the next version.
