I got a Kindle today. I ordered it back in early February, so it took about a month for Amazon to get it out the door. It’s pretty much what I expected. The screen is very readable, in any (reasonable) light. As many others have pointed out, the button layout makes it a little awkward to figure out a good way to hold the thing without pressing either the next page or previous page button. I think I’ll get used to it though.
The built-in web browser is interesting, and might be somewhat useful. Gmail seems to be usable on it. Lotus Notes webmail is out of the question, though. Mobile-friendly sites like http://nytimesriver.com/ ought to be useable.
For the most part, I’m liking it. I have so many hard copy books sitting around that I won’t be using it for most of my reading any time soon, but I’ll start reading something on it soon, just to start using it. I’ll likely blog more about it after I’ve played around with it some more.
