I'm not bothered at all for the iPad - too big for what I want/need in an eReader.
I've had a Handspring Visor for about 10 years now and for what I use it for it's perfect. I know the screen is reflective, but it's not bothered me at all using it either inside or outside at the swimming pool.
Saying that power must be a bugger for the iPad - I use 2 AAA batteries in a month, and my visor cost me $ 25 USD on Ebay
Ereaders have been around for a ling time, no one's just paid any attention to them.
Where'e the smiley face with the jiggly boobs ? That's the one I want.
