It's sized almost identically to the lighted Amazon cover, maybe an extra 1/8" or less on one top and one side. No thicker than the lighted cover. It weighs about 1 oz more than the lighted cover. My cover is one that has the embossing only on the front side. My understanding is that the fully embossed covers are very slightly thicker/heavier and slightly less pliant.
It is larger than the non-lighted Amazon cover, but so is the lighted cover.
My only teensy tiniest OCD complaint is that the kindle sits slightly closer to the bottom edge in the cover, and the artist in me would prefer it sit slightly higher. (I'm weird like that.) It's VERY well protected, in fact I feel like the kindle is BETTER protected in the Oberon cover than in the Amazon cover.
What I liked better about the Amazon cover: (unlit version before it started causing problems) it folded back totally flat and even. It had a very clean look because of the hinge - even if the hinge made me a bit nervous since it didn't totally secure the kindle. I loved the way the strap could wrap the cover in the open position.
I wasn't crazy about the light, even if I hadn't felt like it was draining the battery. It wasn't an even light, and it bugged me to have a diagonal light cast across the screen. I use a clip-on top light now (I have a Kandle, and a Mighty-something or other) and while there's light drop-off by the bottom of the screen, it's straight across, not diagonal. Yeah, I'm picky picky.
