I'm really surprised that Amazon and Barnes and Noble continue to push out eReader devices, and even more surprised that people are still buying them. Two or three years ago, it made a lot of sense, but it's 2012 now and if you want a new eReader, simply go buy one of these for $199:
The reality is that a real Android tablet, like the Google
Nexus 7 can do everything that the Kindle and Nook can - you
can read all existing books from either device by installing
the Kindle or Nook apps. And unlike the limited eReader
tablets, a real Android tablet is... well... a real Android
tablet so you have access to all the apps in Google Play, and
full hardware features - such as a GPS and Bluetooth. For just
an incremental additional cost you get a full blown
tablet-based computing platform.
The Kindle and Nook are very limited, as they only allow you to
install applications from their very, very limited app stores.
There are ways of hacking these devices to install regular
Android apps (I did this on my Nook Tablet), but it's still a
hack - and many applications are still not supported on the
hardware - such as anything requiring a GPS.
There's only one reason I can think of to buy a Kindle or Nook
- if you really want an e-ink display for better viewing in
direct sunlight, in which case it might make sense to buy one
of the e-ink based models, but note that due to technical
limitations of e-ink displays, these units don't have anywhere
near the capabilities of models with LCD or OLED displays.
And finally, yes - Apple is coming out with 7" tablet of their
own, but it will come as no surprise that I wouldn't recommend
it. It just doesn't make sense to pay twice as much for
Apple's proprietary hardware and locked down
ecosystem. It makes me laugh everytime someone tries to plug an
Apple product into anything else, with all the ridiculous
dongles required to convert from industry standard connectors
to Apple's proprietary ones. Enough said about that - do
yourself a favor and buy an Android based product. You'll thank
