When I first bought the Kindle I wasn't really all that excited about the whispernet stuff. I thought Wikipedia search was really cool, but mostly I wanted the Kindle because it had dictionary lookup and content search. Having the Amazon name behind it really helped, too, since I'm a long-time customer and have always appreciated their good customer service. When I actually started using it I really saw what a huge deal it is. It really is so convenient and I think I am buying more books than I would have otherwise. I love the samples, too. I bet you we'll start seeing more ebook sellers doing that soon. I'm surprised it isn't common practice, really.
Give it a few days. You're still playing with all the nifty, new toys. Once you're past that point I'm sure you'll be reading tons of books. I did that for the first couple days, too. The novelty wears off and then it becomes just a really amazingly convenient tool for reading.
