I like the dimensions of Sony's Reader better, but the ability to access blogs and newspapers on the Kindle has seriously tipped the scale in its favor. I've been seriously considering an ebook reader for a while, as I've been doing huge amounts of business travel of late, with a lot of riding in cars, and it'd be glorious to not have to figure out if I've packed enough books for the trip. This is, as all serious bookhounds know, a real problem. A Kindle would take up way less space. And the new text-to-speech thing is pretty damn sweet, too.
Anybody else seriously considering one? I got to check out a Kindle 1 belonging to a friend of badmagic's, and I thought it was pretty neat. I didn't have as much practical use for one then, though.
ETA: Pre-ordered. I HAVE GIVEN IN TO TEMPTATION.
