If you'd like to try what is it feel like using color screen e-book reader -
try Kindle for PC, Kindle for Ipod touch or
Kindle for Blackberry (it's free). If you ask me, I think reading on ipod touch's color screen could kill my eyes ;]) But If Ipad has some glare protection maybe it will be great for reading from color reading screen - like this
wired video about an e-magazine.
