I love my Kindle. All new Trek books are available on release day, and the back catalogue is about 90% available as well. It's absolutely phenomenal for getting out of print trek books without having to go hunting for used copies.
The business model is in its initial awkward phases though, that's true. The removal of 1984 is bizarre, though I would bet money that it arose from a legal loophole they have since corrected. More strange is the total randomness of books that are and aren't available (for instance, an author I love a lot in case you hadn't guessed from my username is Timothy Zahn, and he has a six book series of which the first, fourth, and sixth books are available on Kindle, but not the other three) and the fact that pricing is all OVER the place. Some out of print Trek books are $8, some are like $3.50, and which ones fall into which category seems unrelated to any obvious form of logic.
But similar complaints could've been - and were - made about electronic music when the iTunes store opened, and (though people here are likely less familiar with this) the purchase-and-download computer games program Steam. And after a couple years, they all worked themselves out.
If you're getting an eBook reader right now, make no mistake, you're an early adopter. And the technology does not work perfectly. But even given all those huge caveats, I'm really happy with my purchase, and I look forward to watching the industry slowly make more sense over the next few years.
