Pros:

• Easy to Operate
• Price: $99 is an excellent value.
• Large Screen
• Reads the older .rb Rocket format and dispalys it well. (I can attest to this.) Many free, public domain books are available in this format. Many non-DRM novels also available.
• Reads HTML, RTF and MSWord .doc files. (I have not tested this.)
• Internal modem: Direct connection to your internet based bookshelves via any US phone line. This means you do not even need a computer just to fetch a copy of a book you had already bought.
• Very comfortable in the hand.
• Backlit screen.
• Good third party software for Windows users.
• Different font size - switching to a larger font is easy. The large screen means it can work better with larger fonts
• Web based support for Mac users.

More... 1150 or PDA also the screen

Cons:

• Dependence on Fictionwise/eBookwise for first run ebook buying. I am not sure this is such a negative. Most of the big mainstream novels are going to be DRM'd. That means you will have to buy them from eBookwise. The reason I'm not sure this is so bad is Fictionwise/eBookwise is the biggest player in eBook retail already. Chances are you would buy from them anyway. It is a concern, but in my opinion it is not enough to break the deal.
• No color - screen is greyscale. It is very readable though.
• No Mac Software - they do have the USB driver for Mac OS X, which is critical. But third-party software for Mac OS X is not available as I write this on 11/21/2004
• Medium res (half VGA) screen is fine for text - might not be sharp enough for some illustrations and things like maps.
