The Nook products are the most hackable around. But as a hacker/maker I doubt that we represent more than 1/2 % of the reader/tablet market. I think that the deal breaker/maker with the Kindle is the $79/yr Prime fee. I do not think that the "one free book" per month will contain the top titles. Having a Prime account already this will not be an additional expense for me.

I recommend the Kindle tablet plus Prime to the reader/browser/e-mail/video/music crowd and the Nook tablet for the limited market that needs more power/non-vendor apps/side loading/customization.

I love my Nook Color Gen 1 as an ereader/browser and will upgrade it to the 1.4 software. I will purchase a Kindle tablet over the Black Friday/Cyber Monday period from whomever offers the best swag.
