The Amazon Kindle 4 (aka Kindle 4th Gen, Kindle Touchless or just plain Kindle) was announced as a sidenote to the colour Kindle Fire and touch-enabled Kindle Touch. But in many ways it was the most significant of the three, because of its extraordinary price.
The
UK remains the poor cousin to the US in the world of dedicated ebook
readers. While many are on the market, to be a real success they need
the vertical integration of being linked with a book seller, both for
usability and the subsidy to the initial purchase price.
A
stand-alone reader needs to make a profit for the manufacturer from the
retail price alone, while a book seller device can make its money from
the books and so can afford to be priced cheaply. And Amazon as the
biggest book store can subsidise its ereaders the most.
As a result we really only have Amazon's Kindle, missing out on other book seller-tied devices such as the Nook and Kobo.
Worse,
we currently only have one of the new generation of Kindles, the others
being restricted to the US (presumably for supply reasons). And to add
salt to the trans-Atlantic wound, our new Kindle costs £89 compared to
$79 (around £50) in the States.
But we do at least have one of the next-gen Amazon Kindles, and it's still very, very cheap. So how does it stack up?

Well, unlike the Kindle Touch and Kindle Fire, the plain Kindle is basically a cut down and repackaged version of last year's Kindle 3 - now renamed the Kindle Keyboard - rather than one with new technologies and features added.
That's
not necessarily a bad thing, because the Kindle Keyboard was the best
ebook reader on the market in terms of screen, book choice and price.
If
you put the price of the US version out of mind, £89 really is cheap as
chips for an ebook reader, especially one as accomplished as this.
As
well as opening up ereaders to a new market, when the reader is priced
this low you're less worried about taking it into environments where you
might think twice about using expensive electronics, such as the
bathroom or the beach. While not exactly disposable, it's not £500-worth
of iPad to wreck either.
Amazon
famously sells more books in Kindle ebook format than in print these
days, and this price point is only going to accelerate that trend.
The key to any ebook reader is the screen, and the new Kindle shares
the same 600 x 800, 16 greys E-Ink display as the previous generation Kindle Keyboard, and it remains marvelous.
Its
matt screen surface is perfectly legible in the sort of direct sunshine
that usually reduces glossy-screened LCD devices to pure glare.
However, it's not backlit, so you'll need the bedside light on at night.
Amazon
claims its new Kindle's screen refreshes 10% faster than the last
generation, but we couldn't see any obvious improvement.What has changed
is the visual way the page changes - no longer does the page flick to
all black before redrawing; now only the areas that need to change
flicker and redraw, which looks much more elegant.

A
full-page refresh happens every few pages. The lack of a full refresh
degrades the text quality very slightly over time between refreshes -
you can download a software update to return to the old refresh system
if you find it noticeable.
The screen is the same, but the
packaging is very different. The new Kindle measures just 166mm by
114mm, making it the smallest of the family and some 24mm shorter and
9mm narrower than the Kindle Keyboard, itself a slight device.

Design-wise
the single grey and rounded corners are replaced with a tri-tone set of
greys with much sharper corners. The plastic on the back has a slightly
coated feel to aid grip, but not as rubberised as the Keyboard.
The
buttons are simplified. Obviously there's no QWERTY keyboard, and just
four buttons flank the central four-way-plus-select rocker. The buttons
are Back, Home, Menu and a key to call up the on-screen keyboard.
Forward and back ìpaddlesî sit either side of the screen, and on the
base a simple power button replaces the slider seen in previous
generations.

The
net effect is of a reader the size of a very slim paperback volume of
poetry, which sits in the palm of one hand - if you have fairly large
hands. The reduction in weight to just 170g means you can hold this all
day. The page turn buttons are narrower, so you need to hold the new
Amazon Kindle slightly differently, but we didn't find this a problem.
One change on the back is the addition of two small metal contact pads, presumably to power accessories such as a light.
Inside
the Amazon Kindle, the memory has been reduced from 4GB to 2GB, half of
which is available for ebooks. That's still a huge amount of space,
especially now you can keep any ebooks you're not currently reading ìin
the cloudî on Amazon's servers, and just restore them in seconds. Amazon
reckons you can fit 1,400 books on the device, but we didn't buy quite
1,400 books to check this.

Also
reduced is the battery capacity, but the device should still last a
month on a single charge. No charger is included with the Amazon Kindle,
just a USB cable. But because the Kindle uses a micro USB connector,
you probably have half a dozen compatible chargers lying around already.
The
Amazon Kindle is Wi-Fi only - if you want 3G internet connectivity
you'll need to buy the £149 Kindle Keyboard, or wait for the Kindle Touch to
make it to the UK. 3G is handy, but for most users we suspect Wi-Fi
access will be perfectly sufficient. The Wi-Fi chip is one area that has
had an upgrade, with access via 802.11n as well as a and g wireless
internet.

To keep costs and size down, all of the audio features on the Kindle Keyboard have been removed, so there are no speakers or headphone jacks, there's no read aloud feature and there's no MP3 player.
Most
other software features of the Amazon Kindle are the same as the other
members of the family, but the lack of a hard keyboard means that only
the most masochistic of users will use some of them, such as adding
annotations.

Similarly,
the experimental web browser is still there, but while slow screen
refresh and 16-greys display made it unpleasant to use on the Keyboard,
with URLs taking minutes to type it's virtually unusable here. You might
take the time to laboriously set up a webmail account, we suppose.
The
on-screen keyboard isn't great, the lack of buttons for Shift or to
change to numeric input and the tiny pad making tapping out even
usernames and passwords a real effort. Fortunately, aside from searching
the Kindle Store, once the device is set up you won't have much need
for it.
The Amazon Kindle comes with version 4.0 of its operating
system - the Kindle Keyboard runs 3.3. There are few differences, but
one that the lack of a physical keyboard enables is the ability to
switch languages, which could be useful for multi-lingual readers. A new
set of screen savers are added, which are slightly more contemporary in
feel.

As
with previous versions, you can send your own PDF and text documents to
the Amazon Kindle via email or a direct USB connection. There's still
no direct support for the ePub format, though, requiring another
conversion stage. This is starting to look a little churlish on Amazon's
part. Surely it should encourage users of ePub-based ereaders to
convert?
A significant feature, not just of this device but of the
whole Kindle service, is its ability to share ebooks between readers
running on pretty much every technology there is - PC, Mac, iPad,
iPhone, Android, BlackBerry - you can read the same books, and it
remembers where you got up to on another device. This means you always
have your books with you, even when the Kindle itself is at home.
