Well Bill has one and spoke quite highly of it on the last forum,
apparently you can check you gmail etc on it. Brian also
has one and was impressed with it if I recall.
I guess the 3G comes into its own in that wherever you are you
can buy or download a book, the 3G aspect is free

I would have been happy with the wi-fi one I must admit but seeing
as how I am getting a (hopefully mint) 3G for around the same price
am even happier.
I must admit its the eInk that has always impressed me, as someone
who spends all day staring at computer screens (like many of us) I must
admit that lcd etc screens have always been my number one put off when
considering buying a tablet for use as an ebook reader, I just would not look
forward to looking at one to read.
But I shall see...whenever I get it that is...
