Hey, I recently bought a Crumpler mcbain lovechild 12" bag, Crumpler Schoolhymn 12", Tucano second skin 12" iBook, Tucano Horizontal limit 14"/15". I really wanted the horinzontal limit 12" but a sleeve wouldn't fit inside as well and since I'm anal protective about my ibook (it's my first and only mac) then I want it to be supersafe. Many pics are here since I know when I was lookign for what to buy, it was very hard to find real-life pics. The Crumpler bag is awesome. It's a perfect fit for the ibook and I love carrying it around. The handle at the back is nicely put and handy as well. The bag looks awesome and my friends (many of whom are girls) think it is very fashionable and were like, "wow...that is a laptop bag?!?". Yes, PC users just know of Targus, Kensington, and Samsonite. Sad it is. Oh well. I'm introducing all my friends to these cool, stylish bags. Anyways...the Crumpler Schoolhymn is great as well. It's actually a very hard material, sort of like a minibriefcase. Feels as hard as a textbook cover. Yea, when I stuck my ibook inside it looked a little loose, but I shook it lightly and it didn't seem to move. Seems very protected. Tucano second skin feels like it's too small for the ibook. The little felt that covered the zippers had to be lifted up to cover the underside of the iBook but it was hard to keep the iBook under it completely since it didn't seem to fit properly. I'm not sure. Maybe I need to play with it again. After I zipped it up, it seems to fit perfectly and is very snugly (is that a word?). Anyways, the two zippers is nice compared to Crumpler's one zipper that you have to zip the whole way. The tucano certainly didn't seem as protective as the Crumpler. But honestly, I think any sleeve will protect it. If you happen to drop it, I don't think anything will be able to protect it enough. The sleeve, to me, is just to protect from scratches and contact with other things like dust and crap. And it always feels better when the ibook is completely covered in something. The Tucano horizontal limit 14"/15" is a LOT bigger than I expected. After I stuck the ibook with the sleeeve in there, there was still ample room for an approx 0.5 inch folder. But really, that doesn't matter, since you can still velcro it tighter so the ibook won't wiggle around. As you can see from the pics, I stuck a few things in there. I don't mind having some space in there, as long as its' padded and the ibook doesn't shift around, which I doubt it will, it's fine. The front pocket has a slot for an ipod/mp3 player or a cell phone. There's also a zipper for a pencil case compartment. The rest of the space inside the bag can probably fit 2 mediumsized textbooks plus a 2 80pg coil notebooks. I think ti's enough room for most things. If it's not, stick the ibook in the Crumpler and stick it in a regular backpack. Anyways, I doubt I'll keep all these bags/sleeves (no money) but it'll take some time to think of which one to sell. Anyone interested? lol.
