I read a lot of PDFs, specifically programming books. I like my 7" Android tablet (Kindle Fire 1st Gen) but I find the reading experience terrible in comparison to the iPad 3. There really doesn't seem to be any way to display technical books on a 7" screen unless they are specifically designed for such a task. I had to sell the iPad a while back, so now I may take a look at the 8.9" Kindle Fire to see if it's big enough to properly display my PDFs. While I'm interested in it, there is one thing about the 8.9" Kindle Fire that really disappointed me already. They advertise $50 a year for a mobile connection, but it's only for the first year. When you take a look at the huge price increase between the Wifi and the ATT 3G version, it's not a discount, you are just being forced to prepay for your service. Other than that, it looks pretty nice.
