This column incorrectly said that Amazon.com's Kindle 2 requires that all books obtained from sources besides Amazon must be converted to Kindle format. The Kindle can read plain-text files (with a ".txt" file-name extension) and "Mobipocket" documents (with a ".mobi" or ".prc" extensions).
The Kindle's Reader-Friendly Sequel
Amazon's Kindle didn't make printed books obsolete, and the Kindle 2 won't, either. It does, however, make its predecessor look pretty awkward.
The $359 Kindle 2, which began shipping Monday, is a fine piece of work -- far more elegant than the model that debuted in November 2007. But it still trails the usability of paper in some ways, and it's still stuck in a e-book market that treats customers as potential thieves.
You may not care about those things on first seeing the Kindle 2. Where the old model was all sharp angles and buttons that were either too small or too big, this slim, streamlined tablet (just over a third of an inch thick) looks like it could be the iPhone's big brother.
The Kindle 2's design makes it a far friendlier machine. Its next-page and previous-page buttons fall neatly under your thumbs instead of taking up entire sides of the device. You navigate around the screen by flicking a little joystck instead of rolling a dial to move an indicator up or down a thermometer-style gauge.
That screen uses a faster version of the Kindle's "e-ink" technology. You still wait a second and change to turn a page, during which time the screen momentarily flashes a photo-negative image of itself. But it feels like a notable speedup over the first model. And because the Kindle 2 displays 16 shades of gray, a picture no longer looks like a photocopy of a photocopy of a photo.
This model offers more storage than its predecessor. (At 1.4 available gigabytes, Amazon says, the Kindle 2 can hold 1,500 books.) Unlike the older version, this one doesn't let you expand that capacity by popping in an SD Card.
Amazon says the Kindle 2's battery should last 25 percent longer than the original. But its estimate of "up to 4 days" of use per charge seems optimistic; a day of intermittent reading ran its (non-removable) battery down to the halfway mark.
And the Kindle 2 can read a book aloud in a synthesized voice, which works no better than you'd expect.
In the most important aspect, however, the Kindle 2 is just like the first Kindle: You can get lost in a good book on this thing. The Kindle's minimal, almost-distraction-free interface works quite well in that respect.
And as before, buying titles with the Kindle's free wireless data connection is painlessly simple. You can look through Amazon's inventory of almost 241,000 Kindle books (plus 31 newspapers, 22 magazines and 1,280 blogs) by typing a query on the Kindle 2's keyboard or by browsing through categories.
That catalogue, however, still falls short of Amazon's print inventory. For example, three of the 20 best-selling hardcovers and five of the 12 "Critics' Picks" books listed on The Post's Web site are print only.
Because the Kindle is tied to your Amazon account, you need only select the "Buy" button, and the book should land on the screen a minute later. (Unless you have no service: The Kindle's Sprint-provided wireless access leaves out many rural areas, especially in the western United States.)
