I still haven't committed to buying a Kindle, and Mark Morford echoes of the reasons:
[M]any creators loathe the beige slab because of how ruthlessly Amazon owns every aspect of the experience. Authors and publishers have little control. Readers -- that is, you -- have even less. Want to share a book you finished with someone else? Too bad. Want to upload and circulate your own text without using Amazon's system? Screw you. Want to, well, do anything at all that's not 100 percent within the company's power and revenue stream because you don't actually own any of the books you buy? Amazon says: Bite me.
I like having paper books. I have a sinking feeling that having a Kindle would result in me buying books twice, once for my bookshelf and once to read on a plane.
