Yes.  For example, Gmail users don't know what version number they're 
on.  They're just using Gmail. And the Gmail team (and Yahoo and 
Hotmail) are able to push features without having to use version 
numbers.  "Google Chrome" is another example.

We have surveys and data.  But if we assumed that users want the latest 
and greatest software we could give them, is that a bad assumption to make?

About Thunderbird.  "Thunderbird is up to date".

No, the obvious part and the competition part are wrong.  That was not 
the intent of that sentence.

No I shouldn't.

Here's some reality.  I drive a 2005 BMW X3 not a GM.  There's at least 
two computers on board, one for driving and one for BMW 
Assist/Bluetooth.  I can't tell you what OS they run, what version is 
running on them, but I can tell you that the last time I went to the 
shop, I was updated to the latest versions.  Cool.  Great.

Just like Ford Sync:

I'm not assuming that everybody will be using the latest version.  Plus 
we have data.  86.5% of our users are on the latest version of Thunderbird.

Experience.  Proof.  Talking to our users and potential users on a 
regular basis.
