I have the keyboard version, I find the keyboard is essential for searching the amazon store.
My only problem with it is the battery life isn't great, if you have the wireless internet turned on you can drain the battery in 1 day.
So typically you would be downloading newspapers, blogs etc every day which really eats the battery.
I also have poor eyesight, I find it hard to focus on book pages in the daytime but with the kindle I can focus with no problems all day.
