Kind of on impulse, kind of due to a confluence of suggestions and the current exchange rate, I bought myself a Kindle ebook reader. It turned up in the mail last Tuesday and I've been reading stuff on it happily since then - except for a now quite obsolete feeling paper edition of The Fall, received as a birthday present (note: not quite as original as The Strain was, but just as exciting).
The text is very readable, and seems to be somewhat easier on the eyes than an actual book (and much nicer than an LCD screen). I've been reading faster using it, maybe because you have to do less work (no movement of pages, etc). It has the obvious advantage of being able to hold ~3000 books in a package that is about the size of a paperback, except much thinner and slightly lighter. Another nice service is that many of the Amazon books have a free sample, allowing you to read the first chapter or two of something for free to decide if you want to buy it.
Disadvantages are that the "instant delivery" of new texts makes it easy to spend a lot of money, and that some books are restricted by region, meaning now and again I am prevented by publishing restrictions from giving people money in exchange for their goods. I assume that the publisher and author would actually like me to buy their products, but it seems that some confluence of dumbness prevents this. The screensaver is also a little annoyance, as you can't customize it at all and some of the images aren't so great (particularly the creepy picture of Emily Dickinson.... eek!).
Oh, and it's not going to be any use for pdf game texts, something I would quite like to have available in this format. I think that the ideal electronic device for these is a few years away (or maybe just too expensive - I'm looking at you iPad).
Overall, I recommend the thing. It is good, and means I don't need to worry about getting more bookshelves quite as soon as I might have.
