I have a Kindle Paperwhite. The last two books I've read have been read off the Kindle. It works great for when I can't find books at the library and don't want to pay for them; I just torrent and load them up.
However, e-reading doesn't feel quite the same as reading from a real book. It centers the experience differently.

I have an old Kindle Touch which I jailbreaked and put KOReader on. If you have a Kindle (please don't buy them) I would recommend doing this, it allows you to read ePubs and the interface has way more options than the default one.
I use it for reading most material as I don't like to buy paper books, but if someone has a zine to distribute I'll take it.
