Yes for ereaders - I've wanted the new feature sets. It's hard to see how the PW2 could be improved - I love it, and it 's my primary reading device.
I used the original ipad until last year, and then got the ipad4. Wow - a completely different device! It's amazing. I only use my laptop for photography now. I use the ipad daily, and again, it's hard to see how it could be improved. So I don't have plans to upgrade for a while, but I've learned never to say never
