Legally I don't think it's any different than using Coke or Pepsi. You can mention the product the same as mentioning anything else, but when you make the story about Coke or Pepsi being the main character then you may get into trouble.
If the Kindle is the main focus of the story, you may have some legal obligations. If you change the name of the device, you don't have those obligations.
Edited to add some thoughts to the actual question.

But if your kleenex is actually used by an evil spy organization to transmit biological weapons and the clarinex has been tampered with and the pepsi corrodes the stomach...not quite such a good idea.
Agree with previous poster on the concept of product-as-main-character being a good rule of thumb as well. I'm sure we've talked about this before, search trademarks and copyrights on Hatrack and you'll probably find some good stuff.
But in the meantime, don't sweat it. I recommend search/replace before you submit that story. It'll be fun coming up with a new name...
The reader will know what you're talking about if your story is read in the next ten years. Who knows what will be out there in a decade.
I wouldn't change it until someone paying me told me to, then I'd be all "Sure thing."
If you think it adds to the story, then don't go generic. Who knows, maybe a slush pile reader will read the title, and then remember your story because she was having this exact same discussion in her head.

But I think there may be a problem in that calling it a Kindle, in my mind, sets the story on present-day Earth. Since the story is elsewhere, elsewhen, I'd call it something appropriate to the milieu.
(On the other hand, you could approach Amazon and ask if they're interested in helping to publish the story, given the product placement 'n all ... ;-)

I like the idea of Amazon sponsoring my story, but I somehow doubt they would be too thrilled with mine.
