After having owned three kindles, I have switched to a kobo about a year ago. The kobo has many of its own problems, but it gets the reading experience right: it uses (very un-aggressive) hyphenation, and the lock screen displays the book cover.

I miss going on Amazon, clicking some button, and immediately start reading a new book. Now that's a multi step process that involves a computer and a DRM removal tool. But the reading experience is easily worth it for me.
