I got this for Christmas and loved it immediately.  I waited to review it, because glitches and problems generally show up after the excitement has worn off.  I've had a couple of thoughts of "I wish," but nothing that would make me lower my rating.  Here's what I like--and what I don't:This screen is absolutely beautiful.  I wanted it mostly for books, but videos and content are flawless on it.  The books are beautiful and crisp, too, with plenty of options to change brightness and color.  This cuts down on eye strain.  There is a glare, in bright sun.  This is worse than a regular kindle, but not as bad as most tablets.  I was expecting much worse, with the HD screen, so I've just put it down as the best possible at this time.I wanted this because I'm in college and constantly needing books.  It's faster, easier, and cheaper to download kindle books than to try to buy them in a physical copy, especially when I need  some of the more obscure titles for my classes.  I still have books that I want for myself in hardback form, but nothing beats kindle for college!The build is sturdy, but light.  I don't feel like I'm going to break it if I touch it, but it's comfortable to hold.A lot of people complain about not being able to get Google play content and try to find workarounds, but I don't need that, so it's not an issue for me.  I'd rather buy from Amazon, anyway.  Past experience has taught me that their customer service and quality is superior.  If you aren't like me and you want to be able to access absolutely everything in the world on one device, it might be a drawback.  For me, it's not a problem.  I haven't come across anything I need that Amazon doesn't offer--usually cheaper and/or better then the other guys.I am not very techno-savvy, so it's a plus for me that this device is easy and ready to use right out of the box.  I signed in to Amazon and had everything I've bought in the past at my fingertips.One MINOR drawback is the memory.  You'd think 16gb was enough, but it's only enough if you keep your content in the cloud.  That's fine, if you aren't traveling, but if you find yourself without wifi access you cannot get to your content.  I downloaded a season of a tv show, knowing I would be without wifi, and it really ate up the memory, slowing my kindle fire down a lot.  After watching, I removed the episodes from the device and the slowdown disappeared.  I found myself wishing for more memory, then.  Most of the time, though, I rely on the cloud and 16gb is fine.  I just have to remember that small limitation.  (If I were buying one, I'd go with the 32gb model, personally, and have a little more room to download content for the times I'll be without access.  This was a gift, so I cannot really complain.)  I love the cloud and use it for most things, anyway, so it's a minor issue.  The only time memory is a problem is when I'm traveling.  For some, that might be a bigger issue than it is for me, as it's a portable device.  On my daughter's tablet, which has expandable memory, we are able to download a lot more content and take it with us.  Entertainment is never out of reach, even without internet.  All in all, though, my kindle is easier to work, has a better screen, and is organized better.  Everything has drawbacks.I haven't found anything in the three weeks I've had my kindle fire that would make it anything less than a great value.  I definitely recommend this device.  It has been very helpful and entertaining.
