First let me say that I love my Super Ego and Horizontal Brain Cell. I've had it for about a month now and find it difficult to leave it at home. Anyway, I have a Dell E1405 with the larger battery (85 WHr 9-cell Lithium Ion Primary Battery) which adds about an inch to the height of the laptop, and the Brain Cell is barely able to meet it's velcro mate on the opening flap. I guess I could of gotten a different size??
It would be cool is if there was an extension accessory for the Brain Cells that allows me to fold over the battery.
I can post some pictures if needed.
