After a fairly thorough review of the cases in my local large electronics store (where I looked at about 40 likely fits and tried out the iLiad in a dozen or so), I ended up buying two different cases. The first was a simple sleeve that allows one to carry the reader around without being deathly afraid of dropping it:

No bells or whistles, but extremely light, and the fit is quite good. It definitely serves the purpose of protecting the iLiad while I carry it around.
But the one I’ve actually been using nearly every day since I got the iLiad in August is a camcorder case, also from Case Logic:

I highly recommend this second one, which comes with a shoulder strap and is spacious without being overly large. It has a partitioned smaller space in the main bag where I carry my iPod and cell phone. The outer flap has a zippered pouch where I keep two USB thumb drives I use to shuttle files between my office and home. Below the flap, the padded main bag has a second zippered pocket where I keep a 1 Gb SD card and a 2 Gb CF card—which I use as two different ways for expanding my iLiad’s storage capacity. What’s really good about the system is that there’s always room to add another device or card in a pinch, and the cards I carry themselves offer plenty of additional space to store files I want to have available—for whatever work or personal projects come up. This storage scheme lets me take full advantage of the iLiad’s ability to read a wide range of storage formats.
With the iLiad having done away with my need to carry paper back-and-forth and this bag having given me the ability to carry the other things I was using one for, this arrangement has allowed me, literally, to get rid of the briefcase I was carrying back and forth every day--and at about a tenth the weight.
I got both of these from Fry’s Electronics, but I’d imagine you could also find them at your own big electronics/computer store of choice. If all else fails, you can order direct from Case Logic, through the links above.
