worth buying" isn't automatically synonymous with "iPad."
It's heavier and slower than the Nexus 7, and although it runs a
version of Android, it doesn't have access to the vast universe
of Android apps. But if you've got a confirmed Amazon- lover on
your list - especially one who already belongs to Amazon Prime
and can take advantage of features like the Kindle Lending
Library - this may be the tablet that warms her heart.  An
alternative is Barnes & Noble's new Nook HD. It lacks some of
the Kindle's extras, like a front-facing camera. But it's got a
better screen and no ads - unlike the Kindle, where you have to
pay an extra $15 to escape what it euphemistically calls
"special offers."  Ama
