The very point of no longer sending the verison in the user agent is to 
make it difficult for websites to determine the operating system 

We already have to deal with enough serious web compatibility problems 
caused by the rest of the information in the user agent. I'm pleased 
that the version number is now stable -- that's a huge improvement -- 
but I won't be happy until Safari and other major browsers start 
sending fully-randomized UAs, or else a stub or blank UA
