Kindle DX Review

I recently took the plunge and bought the Kindle DX (Global Wireless) from Amazon.  Most of the books I read are typically 1000 pg technical reference type books that just take up too much room and are cumbersome to haul back and forth from work to home.  For me, the benefit is having pretty much all of my reading material on a device that is no larger than a National Geographic magazine.  I can search a keyword or phrase in 1 book or all of my books at the same time.  This technology could be a huge benefit for college students, business travelers, or just anyone with too many books and not enough space(like me).

The hardware

About 1 month after pre-ordering the Kindle DX (Global Wireless), a small little box arrived in the mail.


Inside the little box are only 3 things (Kindle DX, USB/Power cord, User Manual)


Here are some different views that you may find helpful.

Now that I’ve had the Kindle DX for a couple weeks I thought I would share some of my own findings:

  • Download time for the local newspaper (The News & Observer)….about 1 min. Noticed that the daily and the Sunday paper are both $.50….Bonus!
  • Download timer for a larger 1000+ page book with diagrams, etc….(Cisco Press) ….about 10 min.  I should note that I purchased the Cisco Press as I was leaving for work.  The Kindle DX was on the passenger car seat downloading while commuting to work.  About 10 min into my commute I looked down and saw the new book.


  • Download time for a small 400+ page book was only 30 seconds…..The Art of War, by Sun Tzu.
  • Reading PDF files is a snap.  Just drag the PDF file via USB from your PC to Kindle. Or you can email a PDF file to your Kindle for a fee….$.15 per megabyte while inside the U.S. wireless coverage, $.99 per megabyte outside the U.S. Password protected PDF files are not supported.  You can rotate the Kindle to view the PDF file or any page horizontally if you like. This seems especially helpful if you are reading diagrams, flowcharts, etc…

  • Text-to-Speech function: I would give this an OK, though I probably won’t use it much.  The voice is not like the narrated voice of an audio book.  The voice is similar to that of the turn-by-turn directions you may have on your GPS unit in your car. It’s kind of a choppy,mechanical sound, that will sometimes mispronounce words from time to time….but it’s just fine if you’re just wanting to get the gist of a newspaper article.
  • Dictionary: Awesome!  Just put the cursor in front of the word, and the Kindle displays the definition instantly at the bottom of the page.
  • Weight: Some people say the Kindle DX is heavy.  It’s not heavy…certainly not heavier than a book.  18.9 ounces.
  • Bookmarks/Notes:  Very easy to add and search on for later reference.
  • Kindle DX automatically bookmarks your last page.  You can power off, power on, and pick up right where you left off.
  • Search function: Locally, Kindle Store, Google, Wiki, Dictionary, Notes.  Simply start typing a word or phrase and a box pops up at the bottom of the screen.  Click search within any of the above sections and a list of results appears.

  • Samples: You can get a sample download of a book/newspaper, etc for free to make sure it is what you want before buying.
  • Accessing the Web:  This function is still in experimental stages, and really only useful on websites with mostly text based content.  Flash animations, etc are not supported and do not show up.  This will work ok in a pinch, but your browsing will be better on your laptop or Smartphone.

Overall, I would give the Kindle DX 4 out of 5 stars.  The price at $489 from Amazon is pretty steep.  The browser needs some work.  Hopefully in the future, the browser will include flash animation, so most websites will not be so cumbersome.  I can’t really say anything negative.  The screen resolution has amazing clarity.  All of the search functions, menu changes, and page turns are very responsive.

    I’m in networking and have had reservations about trusting a kindle to the same book(s) you are showing in the picture in the review. Can you share some of your experience with Cisco R&S and CCIE study books and how they look on the kindle? drawings? Does the lack of color make the artwork suffer?

    For “Cisco Press” size books, I think the Kindle DX works great. The screen size is just a tad smaller than that of the Cisco Press books. The lack of color is not an issue at all. I think it has something like 16 different shades of gray. I have not seen a picture yet that was not viewable. And for smaller diagrams you can just flip it sideways so the larger diagram will show up horizontally.

    Other things I’ve noticed:
    Sometimes if you know exactly what you are looking for in the book, pdf, or whatever, the book version is faster b/c you can just thumb to it knowing that topic X is in the middle of chapter 7.
    However, lets say you’re studying, and you’ve got something like 10 different books on your Kindle, and you vaguely remember reading something about this topic, but you just can’t remember where you read it…You can just type a key phrase like “IP community list” and find that this topic is in the CCIE R&S Exam Cert Guide book, and there something like 7 different paragraphs. Pretty cool!

    Anyway Hope this helps.

    Have you tried the Safari online books? I wondered how the online Cisco books look.
