for me i prefer hardcover because it last longer...

Softcover, large print. I always read in bed and softcovers give more flexibility for ...eh.... change of positions.

easy to bring around.

softcover, mass market paperback editions. easier to hold and carry around. BUT, i do keep hardcover editions of the titles i really like.

Paperback, due to size considerations. Hardcover is only for books I really want & have been waiting for some time. Oh, and if the release is not so frequent (ie Wheel of Time. Malazan Empire books). Not so for books that are released fairly frequently like Discworld series etc.

prefer softcover, but i bought hardcover for my harry potter books for all the obvious reasons.

hard cover a bit too nice that i'm too careful with it.. makes reading inconvenient... plus so much more expensive

softcover!! because it's lighter...

Softcover better easy to hold and don't make the hand pain^^

Paperback.. Why? Because it's usually at least 50% cheaper than the hardcover. lol.. Price notwithstanding, I'll take hardcover any day.

Softcover for the ones i read and forget (easy to carry around too!), hardcover for the ones i collect, read and re-read again and again

softcover paperback.. cheap and fit on my hand

Hardcover for my favourites while soft cover for normal read..generally softcover is better..cheaper also..

hardcover only if there's a book signing.

softcover, due to price, flexibility and feel

softcover of course. Books are expensive, and hardcover more so. hehe

Soft covers for practical reasons. I do most of my reading while waiting and I can carry a soft cover wherever I go with me.

Buy softcover and then wrap up with a hard plastic to get hardiness to it. Softcover too easily get dog-earred.

Softcovers/paperbacks mostly.

I'll buy hardcovers of my favourites. Trade paperbacks are also cool..

Paperbacks! Easier to turn the pages while reading on the bed. =)

But, but, hard covers will look like an ancient tome when everything oxidizes. Cooool.
