I noticed that you have an EB1150 and a Kindle, both of which have dictionary lookup support. The Sony doesn't. Do you use the dictionary often?
Yes, the Sony is enchanting, but be sure that it does what you want it to do, before you decide to buy it for its looks ("Never judge an ebook reader device by its cover!"

) I decided on the Cybook because I use the dictionary ALL the time on my EB1150. It's incredibly useful to me, and I wouldn't want to be without that option.
