Whie these articles are great (and thanks for it), One of the biggest reasons I am excited about Firefox OS is the aim for these articles to not exist, if you do a good job building a mobile friendly web app then on Firefox OS it should 'just work'
The amount that this has proved true already is amazing, I have loved doing Firefox OS app days and seeing people spending a long time building phonegap / mobile web based applications and seeing it just work on Firefox OS, there is still a lot of work to be done but it really is the ubiquitous platform dream of mine come true.
