We had an email last year asking for input on which platform to develop on this year so it's also the students' decision to learn Android.
Most would prefer to develop for the iPhone, and are taking steps to gain access to Macs and developer accounts for that purpose. This will be a nice push in the other direction.
By all means teach your class Android if they want it, but don't use _this_ article as proof that they should.
That does not, of course, necessarily filter into intro CS classes. I have seen a few "mobile development" classes in universities, but they seem to be split between iPhone and Android.
