My Two Cents:
What it comes down is how comfortable the ereader is to you. For me, the kobo was the right weight and had the soft backing, so I decided that over ease of navigation. The kobo is slower and not as robust in functionality, but for me it was great. Go to a Borders and just hold and read a page or two of these two products. They are awesome, and once you go ereader, you wont go back....I promise
