Not high-priority, but since we don't support the vast majority of platforms detected in this file, I think it should be simplified.

You could probably get away with something as small as this:

```JavaScript
function getOSName() {
  var platform = navigator.platform;
  if (/^Win/.test(platform)) {
    return "Windows";
  } else if (platform === "MacIntel") {
    return "Mac";
  }
  return "Other";
}
```

In fact, removing this function/file entirely and inlining the logic into the homepage might be wise given how small this is.
