title: HttpBrowserCapabilities missing some information?
body: <p>I'd like to use the <code>Request.Browser</code> property (<code>HttpBrowserCapabilities</code> class) to determine some properties of the client's system.</p>
  
  <p>However I seem to run into some limitations of this class. I can't find some properties that should be relatively easy to parse from the <code>UserAgent</code> string, like the OS version (<code>Platform</code> will only return WinNT for most Windows versions, but not Vista, XP, etc.) or whether it's x64 or not (only <code>Win16</code> and <code>Win32</code> properties).</p>
  
  <p>I would have expected to see these properties in the <code>HttpBrowserCapabilities</code> class, because most other user agent information is there. Am I missing something? Can I find this information somewhere else? Or should I just parse it from the UserAgent string myself?</p>
