Concerning trend in both OS, and hardware race

I just saw this post on BGR (sorry Verge) http://www.bgr.com/2012/04/19/htc-usage-share-drops-60-in-five-months-study-finds/ that shows the continued decline of HTC's usage share. With Blackberry all but dead, and Windows Phone 7 not exactly blazing up the market, it feels like not only are we heading towards a two horse race between IOS and Android, but that there is a continuing trend towards a two horse race between hardware manufacturers as well - Samsung (Android) and Apple (IOS). This is discouraging news on both fronts. Am I over reacting, or do others fear this as well?
