Ipad worthless?

I purchased an Ipad shortly after they were released. I spent $500 on the new Steve Jobs wonder toy. I didn't see a need for the 3g version since I already have an iphone, and I saw no point in paying for more storage since most of the time I have a laptop with me as well. When I first bought the Ipad, I used it every day. Since then, I've used it less and less. I realized today that it hasn't even come out of my bookbag in 2 to 3 weeks. It seems that what I thought would be a very useful tool has turned into a somewhat worthless toy. Anyone want to buy an Ipad?
