I agree. Microsoft, Apple, and Google have the ability to modify user behavior without much downside. The rest of us are better off making the user experience as fast, efficient, and simple as possible.

By coincidence, I just put a 301 redirect on my personal site to go from www.xpda.com to xpda.com two days ago. If I could only get ctrl-enter to submit https://domain.com instead of http://www.domain.com in Firefox, I'd be happy. (There was a bug that prevented this last time I checked.)
