To each their own I guess. Personally I love how awesome it is that I can have one book in many places. I can read from my laptop at work, on my phone on the go, and from my tablet at home. Each automatically syncs to the last read page and my notes/highlights move between them. Mind you I don't actually ever USE notes or highlights, but it's pretty cool that that option is there. Sure I like to hold a book in my hands, but the convenience of an ebook is really hard to beat.

Plus if I have a moment to read and I want a new book, I don't need to wait 3-5 days for shipping, I can download it instantly. If I'm ever out of the country (as I am now for half a year) I can still get any book delivered to me instantly. For me that's just a convenience, however it's critical for areas that normally have to wait 15-20 days for shipping from a place like Amazon.

EDIT: As a quick note to your edit, you're really ignoring some of the best parts of ebooks while pointing out their worst. I don't own a Kindle however read ebooks through Amazon on three different devices.
