Kindle Keyboard 3G

Kindle Keyboard 3G
Price £149

Pros: If you're going to be making a lot of notes then it can get time consuming without a proper keyboard. Although, depending on how you type, you may find using the mini keyboard not much more help than using the on screen one.

Cons: If you aren't going to be using a keyboard a lot, you're really better off with one of the other models, as the keyboard makes the eBook reader substantially bigger and clunkier (19 cm x 12.3 cm and 274g compared to 16.5 cm x 11.4cm and 170g for the basic model).

Ideal for: Undergraduates, those working on a PhD and others who do a lot of research for work (or pleasure).

Suggested eBooks: You've presumably bought one with a keyboard for a reason - you like writing. Have you ever thought about writing your own book and publishing it on Amazon? It's an easy process and you can learn more about it here.
