Kindle Fire HD Vs. Kindle Paperwhite 3G?

[Jensen]

The Paperwhite will work more or less for webmail, twitter etc, but better if using the mobile versions of those sites. However you can only access those sites when using wifi on the kindle, not the free 3G.

As you say you have the galaxy anyway which does pretty much everything the Fire does so unless you have a particular desire for that fancy new gadget there's no real need.

For actual reading, you can't beat the Paperwhite - perfect screen for reading text and the battery lasts for much much longer than the Fire or any tablet and of course it's much cheaper than the Fire.
