I've decided. I will buy an ereader after the first of the year. Prices are expected to come down when new models appear, and I can take my time making up my mind. So I'm okay with waiting.
After an exhibition by our computer club, I'm leaning toward a Kindle. But I'm still open to other arguments. Right now I've heard from people who have the three in the title. Each one loves his/her device. I'm thinking since I don't really want to do much more than read with one, the Kindle will serve the purpose.
Of course, once I get one, I'll have to wait for our library to get into the ebook business. But they will, I'm sure. Just a matter of time.
