Kobo Aura is the latest edition, based on Linux platform, is slightly larger at 5.9" x 4.5" x 0.3" and with 4gb memory instead of the 2 gb memory.

Aura also has better battery life and comes with pre-installed games like chess.

I personally prefer Kindle though. Just a suggestion. It is primarily because Amazon has a large collection and comes with offers every now and then. There are also Indie authors that publish there.
