I've been reading electronically -- phone, desktop (I know), Kobo, Kobo Touch -- for perhaps two years now, and I've come to the following conclusion as my reading habits have changed. Electronic reading does a better job of engaging the reader's imagination than print books do.

It's also, of course, a more physically pleasurable experience:

Lighter
Easier to operate (I'm talking about turning pages, and believe me no one is a better one-handed print page-turner than I am)
Less likely to wake you up when you drop it on your face when falling asleep reading
Not going to bedazzle you with glare when reading in bright sunlight (seriously, reading a good e-ink display beside a pool is a world-class experience)

But all of those are ultimately secondary. What eReading is really, really good at is letting you be a creative reader. Reading is the act of imaginatively interpreting -- reconstructing -- the work of an another person's imagination. That's subject to two sets of constraints: the range and ability of the author to express their imagination; and the range and ability of the reader to interpret it, which is to say, to creatively reimagine it on their own terms. Technology is not a neutral factor in that relationship. And electronic readers do a better job of relaxing the second set of those constraints.

Here's what I've noticed about my reading experience over the last couple dozen months.

1. I'm reading more.

Having a vast array of content to choose from means less reading time lost because I'm not quite in the mood for the book that I happened to bring with me. And that's exactly the point: I can read according to my mood -- not have to remember to bring a book strong enough to change my mood. Every time.

So, I'm better read -- but also have the ability to start reading something on a spur-of-the-moment suggestion. If I'm at a party and someone says, look, you have to read The Poisonwood Bible, I can start reading it on the bus on the way home instead of the Pretty Little Liars #9 that I was reading on the way there. This possibility, alone, makes me feel better read, because it's always within reach. The horizons of my imagination feel broader. (It doesn't hurt that the prices are usually lower.)

2. I'm far less tolerant of poorly written non-fiction.

Perhaps that's not quite fair: I'm far less tolerant of non-fiction that is written without a distinctive voice, or at the very least some concession to narrative structure. For all the improvements of scrolling and progress indicators, it remains much easier to skim a print book than an eBook. Which means I have to page through the eBook... and if it's boring I'd just as soon move onto something else. But on an eReader, the abandoned books aren't staring me in the face in some strange transfiguration of guilt and anxiety. In short: I'm in control of the reading experience -- unless the author is really, really good; unless they are actively contributing towards the mutual creative act.

Perhaps we do lose something in that. "Great books don't promise to hold your attention," I remember an English professor once telling a class utterly bored by one of the masters of American literature (probably Dreiser), "but they do promise to reward it." I suspect that, in a future when electronic reading is the dominant manner of reading, authors who can't write well will not be able to release ideas slowly. (And if we don't read Dreiser, we'll all miss out on some of the more amusing fender-benders of American prose.)

On the other hand:

3. I can concentrate better

Somehow the flexibility of the form -- yes, the font size, the typeface selection -- means that I can get better terms in the reading relationship. I can take my glasses off but still read without having to hold the device a couple of inches from my face. It's less about the conditions that I must arrange in order to read, and more about how I can manipulate the content to suit me.

4. I don't feel like I'm carrying a book around

Because I'm not. I'm not carrying hundreds of books either. At a certain point, having more books than I could list made my device something less like a book, or a compendium, than a portal: a door. That was one of the thrilling discoveries of the first Kobo reader: it came pre-loaded with a hundred free books, which made it clear that this technology was not simply a more efficient distribution mechanism, but a gateway to limitless content. Wi-fi devices have absolutely helped with that too -- but they have kept the connection to the wider Internet obscure enough that I'm not prone to jump on Twitter or the web. Reading remains immersive, yet feels connected.

5. The books I have read feel closer to one another

And that sense of connection, crucially, extends to the books I have already read. Somehow the ability to have the complete works (well, not quite yet) of Faulkner, Didion, Murakami, and John McPhee in my bag, at all times, gives me a more holistic sense of my reading life than having them marooned, out of reach, on a bookshelf, where their valences are confined to the sequence in which I happen to have them shelved. The connections between these books are multiple and they continually expand as I -- by the sheer act of reading -- add to their company. Virtual shelves aren't the same as real shelves, and the books I have on my Kobo live in the same kind of unregulated relationships to one another than they do in my imagination.

By amalgamating possibility, your aggregate reading experience, the range of your reading and your interests, electronic readers offer a sort of physical external representation of your imagination. They are a sort of auxiliary imagination. My Kobo Touch, after only a few weeks, houses hundreds of books and hundreds of annotations and highlights; it has measured and marked my progress through novels and essays (and, yes, I earned the insomniac badges along the way). It hasn't just been a device: it's been a companion.

Reading merges the content of the page with everything else you have ever read, through the filter of your imagination. It is a cumulative, messy process: it disintegrates the boundaries between ideas, times, places, people, events. It is a process of unseaming the constraints of reality; of unspooling it into the collective and personal reaches of the imagination. And the eReading device is by definition a much better metaphor for that process than physical books. Ideas collide, aggregate, pile into one another. They are sunk within you. They do not remain distinct.

Perhaps this is how the listeners to epic poetry once felt, as the stories that are now The Iliad and The Odyssey were released into the collective ether. Perhaps physical books were a transitional media.

So that's where I'm at. Admittedly other things have conspired to bring me there. I'm not at a point in my life where I still strongly feel the need to display my books around me as an expression of my refinement and taste, and in any event it's rare that a book changes me in the way of a Slouching Towards Bethlehem or Light in August: my imagination is more robust than it was when I was 21, and I've already discovered many of the books most likely to change me. What's more, the limitations of urban living have somewhat necessarily curtailed my ability to endlessly collect books.

But still: I've fallen out of love with shelves of trade paperbacks, and back in love with something that feels closer to the experience of reading itself.

Reading a physical book still retains its pleasures: there is absolutely something thrilling about a gorgeous hardcover, something that feels like a communion close to the author's intent. But that's exactly the point: physical books make you read on the author's terms; reading electronically takes place more on the reader's terms. I think that's a good thing. It makes reading more personal, more democratic, more controversial.

But it's a huge change -- and it could be a generation before authors catch up to it.
