I’ve been thinking about that, actually, and I’m really interested. The Kindle is particularly tempting. It seems like they’ve got the form factor (mostly) worked out, and it ought to work for me most of the time.
Here’s the thing, though: 99% of the books I read now come from the library. I almost certainly wouldn’t buy as many books as I want to read. Most of the time, these days, I read a book just once and don’t see any particular need to have it around to read again. Of the (80+?) books I’ve read in the last year, I can see owning less than 10 of them, including cookbooks & how-to books. The library meets my needs perfectly that way.
Yes, my library has e-books. Unfortunately, they use @%&#*ing Overdrive, which has a meager selection and doesn’t support Kindle. (Or at least it didn’t the last time I checked, which was probably a month ago.)
So until I can check out library books (or there’s a good cheap rental solution), I just can’t justify it. Alas.
