I just got my April Kindle royalty payments (thanks Kindle readers, especially in the UK) and it happens to coincide with my decision to buy a new ereader. I enjoy my iPad, but it's too big to stick in my pocket or carry to the gym. I almost bought a Kindle, but the only ones at Walmart were the ones "with special offers." If my device is going to act as a rolling billboard, they're going to have to pay me a hell of a lot more than $25.00 for the privilage. I think I would pay twice as much for the non-"special offers" model.
Then Barnes and Noble announced the new Nook. I wasn't that impressed with the original Nook, and don't care for a Nook 2 since I already have an iPad. But the new Nook has some very cool features-- a screen similer to the Kindle, only with touch, the ability to add your own screen savers, and it is very small. It won't be out until June 10, though so I have to wait and check it out before I buy one.
