I'm considering purchasing an iPad. A friend of mind brought his into my office and I was seriously impressed. I've since learned that over 4,000 resources are available for the iPad so I'm assuming most of my resources will beavailable to me on the iPad. My question is about speed and battery life. Can someone who owns an iPad comment on how fast it is and the typical battery life you are experiencing. Any quirks or irritants I should expect? Thanks for any and all comments.
