I have an iPad and a kindle and I love them both!!
WE are huge Apple fans and have just about every Apple product there is!

So, when they came out with the iPad we had to have it too!
I love my iPad for going online, checking email, having my music and photos on it and the tons of cool apps. There is just so much you can do with it. If you do want to get one, wait until April when the iPad with the built in camera comes out!
I used my iPad for reading for a long time and swore I didn't need an ereader. I had the Kindle app, the Nook app, the Borders app and iBooks. I used them all and loved it. Yes the iPad is a bit heavy after awhile of reading. The biggest downfall of using it as an ereader is that you cannot use it outside! I tried using it in the sun and you can't see a thing.
So, I finally got the latest generation Kindle and I love it! It is so easy to use, lightweight and easy to read. I wear glasses and being on anything backlit like the computer or iPad, for too long and my eyes start to hurt. Not on the Kindle!
So personally I would say get both!

. But, since you have a net book, and laptop I think you should get an ereader. My personal favorite is the Kindle over the Nook.
