So how big is an 11.6" netbook?
I've found that I usually have to encounter a laptop in person to get a good feel for its size, but I'm hopeful the pictures below will give you some sense of the size of these two systems, along with their styling.

The Aspire One 751 with my fairly average-sized hand modeling for you

The Aspire One 751 (bottom) is just a smidge wider the Eee PC 1000H (top)

The 751 (bottom) is ever so slightly deeper than the 1000H (top) but obviously thinner

The 751 (top) and Gateway LT3103 (bottom) share nearly the same dimensions

The Gateway's six-cell battery (bottom) makes it thicker and deeper than the 751 with the three-cell battery (top)

The LT3103 is still fairly compact, though

The ports on the angled corners of the 751 are an eye-catching touch

The LT3103's look is more traditional but generally tasteful

Hey, I said generally tasteful

I don't have much to add to the pictures above. I believe you can see the placement of the ports and such on both systems reasonably well. Although they differ somewhat, I have no complaints about either. One thing you can't see in the pictures above is the Wi-Fi switch, which is on the front left of the enclosure in both systems, beneath the edge "lip" of the case.
