It looks to me like pinch/zoom doesn't work. Not a big deal, but I wouldn't call it perfect until it's flawless on a tablet and phone.
Here is the code:
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=0">
Removing that little "user-scalable=0" should fix it, as being able to zoom in on a page is a nice feature, and shouldn't be disabled unless there is a really good reason.
