Hi Sharon,
I agree with those who have posted/commented that reading a novel on a computer screen is a struggle at best, and painful to the eyes at worst. That said, I love your Liaden work so much that I read the first serialized novel on PDF for hours straight, and just took tylenol for the eyestrain and headache that I got from doing so.
Call me a luddite if you will, but I prefer having an actual book in my hand to read when I sit down to entertain my weary self, and I don't think that will ever change, no matter how many Kindles or E-readers with bigger screens they come up with.
Sadly, due to the economy and my chosen profession (journalism) I've not been able to afford to buy as many books as I used to, and that includes buying books online or paying for serials.
However, when things start turning around in this recession, I do plan to make a 'donation' for Saltation, though I've not read any of it yet.
I think that your Duanfey and Longeye books are good reads, as well, and I hope to get a copy of Longeye one day soon.
