When we design new layout, we need to find out what kind of users are using our website.
The easies way is to parse User Agent string, but it isn't easy.
Just look on following links:
- http://googlewebmastercentral.blogspot.com/2011/03/mo-better-to-also-detect-mobile-user.html
- http://www.useragentstring.com/pages/Mobile%20Browserlist/
- http://detectmobilebrowsers.com/
- http://techbrij.com/display-mode-mobile-tablet-tv-aspnet-mvc
After few tries I ended with last link, which gives me enough result approximation :)
