Well, the thing is there is rumor of a KindlePad of some kind coming, so think of that. Also, did you see the Amazon Kindle news for today? Massive sales. I've never been an Amazon fan but I had to acknowledge what just happened today: http://ipadtest.wordpress.com/2010/07/19/this-settles-it-kin...

And, here's a post from a writer publishing directly through Kindle who is very pleased with the money he's making: http://jakonrath.blogspot.com/2010/07/with-change-comes-ange...

I'm not advocating for Amazon. Just giving you some stuff to consider. Good luck.
