If you ever use SQL Server Management Studio, you can experience the opposite. Whenever there's an update, you'll get a notification in the application, but to actually install it, you need to go to Microsoft's website to download the latest version and install it yourself. Chrome, on the other hand, updates itself upon restart without requiring anything special from the user.
As a software developer, I really like that part. It means that websites I work on only need to consider the features supported in the latest version of major browsers rather than the last several (as was the case with Internet Explorer).
So, it's nice and something that I remember really appreciating when Chrome was getting popular. But it's still a weird thing to brag about.
