To paraphrase radio show callers: 'Long time reader, first time submitter.'
I would not even consider an e-Reader without an integrated dictionary. I think it is required functionality, not an option. Currently I am reading Moby Dick through DailyLit (
www.dailylit.com - Usual Disclaimer) in my laptop while using Outlook. It is incredibly enjoyable being able to lookup a work without changing applications or pages.
