Kindle 2, DX Review Contrasts

Can we gauge anything from the kindle 2 and dx review number and ratings? Perhaps.

Kindle 2, DX Review Contrast – Number of Reviews

503 Kindle DX Reviews.

  1. Days for which pre-orders were available – 35. May 6th to June 10th.
  2. Days since it started shipping – 67. June 10th to Aug 16th.
  3. Reviews per day since it started shipping – 7.5.
  4. If we assume 1 out of 100 people add a review – 750 Kindle DXes sold a day.

That would mean total sales of 50,250. Let’s multiply it by a factor of 1.25 to account for orders that haven’t reached yet due to delays etc. and we get 62,812 sales. Good, not overly impressive.

5,668 Kindle 2 Reviews.

  1. Days for which pre-orders were available – 15. Feb 9th to 24th.
  2. Days since Kindle 2 started shipping – 187. Feb 24th to Aug 16th. 
  3. Reviews per day since it started shipping – 30.41.  
  4. If we assume 1 out of 100 people add a review – 3041 Kindle 2s sold a day.

That would mean total sales of 568,667. Lets multiply it by 1.1 to account for newer orders and other factors to get a figure of 625,533. Very impressive.

Of course, you could assume 1 out of 10 people add reviews and guesstimate sales figures at 6,281 for kindle dx and 62,553 for kindle 2.

Kindle 2, DX Review Contrast – Ratings

503 Kindle DX Reviews, with -

  1. 5 star kindle dx review – 215. 
  2. 4 star kindle dx review – 109. 
  3. 3 star kindle dx review – 63. 
  4. 2 star kindle dx review – 20. 
  5. 1 star kindle dx review – 96. Actually, if you exclude the anti-DRM reviews you are left with something like 30.

That equates to  -

  1. An average rating of 4.05 stars. Not far off from the 4.12 stars rating across the first 100 kindle dx reviews.
  2. 74% of actual owners giving the kindle dx 4 stars or 5 stars.

5,668 Kindle 2 Reviews, with -

  1. 5 stars – 3,314.  
  2. 4 stars –  1,007.
  3. 3 stars – 322.
  4. 2 stars –  218.
  5. 1 star – 807. Lets assume half (407) are legit owner reviews (pretty conservative).

A lot of the 1 star reviews are from non-owners. The anti-DRM people chimed in here too. However, there’s no way to go through 807 reviews so we’ll stick with the 400 fake reviews figure.

Equates to

  1. An average rating of 4.25 stars.
  2. 82% of actual owners giving it 4 stars or 5 stars.
