I have now been using the Kindle Fire for about a month. I thought I’d weigh with my impressions thus far. This isn’t intended to be a thorough, technical review. It is simply my view as a publishing professional and e-reader enthusiast.

I have been a fan of the Kindle since Amazon introduced it in 2007. I have bought every iteration since then and have been pleased with the evolution of the device. The simplicity, battery life, and integrated buying experience have been delightful.

Last week, FrugalDad published an amazing graphic about Amazon. Since 1994, Jeff Bezos, the CEO, has steadily grown the company. I knew it was big, but I had no idea how big.

This infographic is worth studying in detail. No author, retailer, or publisher can afford to ignore this behemoth. (Don’t miss the question at the end. Please leave a comment! I’d like to know what you think.)

When I read anything, I mark it up. Margin notes, circles, and, most of all, highlights. In fact, I buy highlighters by the box. Or at least I did, until I started reading so much on my Kindle.

Now I use the Highlighter feature of the Kindle to mark passages. I also occasionally use the Notes feature to record my thoughts about a passage. (This is actually pretty cumbersome on the Kindle itself. I usually only do this if I am reading on my Mac. Then I can use my keyboard.)

Last week I attended Digital Book World in New York. More than 1,300 industry professionals showed up, doubling last year’s attendance. It’s clear that digital represents the fastest growing segment of the book industry, but will it grow as fast as industry executives think?

Forrester Research presented a fascinating study, based on a survey of book publishing executives. One conclusion was that “by 2014, [publishing] executives predicted that half of units sold will be e-books, although it was not clear at what price e-books will be sold.”

When Apple launched the iPad last spring, most everyone assumed it would kill the Kindle. After all, the iPad had a multi-touch screen, a crisp, color display, the ability to view books, photos, and movies, and run thousands of applications.

For Amazon, this seemed like the classic David vs. Goliath scenario—the single-purpose, underpowered Kindle against, the multi-purpose, powerful iPad.

Because I am in the publishing industry, and because I have written extensively on the topic of digital publishing, I get asked several times a week, what e-reader I recommend. Frankly, I’m probably not the best person to ask. I experiment with all kinds of technology and am very fickle. I am always trying something new.

So, rather than simply offer an opinion, I spent Saturday morning creating a spreadsheet that compared the four major e-reader brands, representing a total of ten models. I included the Amazon Kindle, Barnes & Noble Nook, Sony Reader, and the Apple iPad. (You can download the actual spreadsheet here or the PDF.)

Yesterday, I received my Kindle 3. It was all I could do to keep from opening the box. However, I wanted to share the “unboxing experience” with you, so I waited until I got home so Gail, my wife, could video tape the whole thing. (I did the same thing with Kindle 2.)

This is now the third Kindle I have bought. You’d think Amazon would send these free (hint, hint) to major publishers, but they don’t. The good news is that my Kindle library migrates effortlessly from device to device. In fact, I can even read my Kindle books on my iPhone, my iPad, and my Mac.

Make no mistake about it: I am an Apple fan. I own several Mac laptops, iPhones, and iPods. I even bought an AppleTV—and love it. When the iPad was announced, I watched Steve Jobs’ announcement and the online Guided Tours. I ordered one the first day I could do so. I purchased the 64GB WiFi (non-3G) version.

One of my primary sources of information about the book publishing industry is Publishers Lunch Deluxe. It is published every workday by PublishersMarketplace as part of its premium membership service. If you are an author, agent, or publisher, it is must reading.

I bought the Kindle 1. Then earlier this year I bought the Kindle 2. I was enthusiastic about both devices. But after nearly two years of using them on a regular basis, I have to admit, I still prefer bound books.
