I hope this goes well. I got excited about using web technologies to build native mobile applications with WebOS, but am happier to see the non-profit Mozilla take charge on it.
I also agree with other commenters that it's a great idea for them to attack the emerging markets rather than compete with the huge players in the US and Europe. Excited to see that revolution.
I've always supported Mozilla's mission, but I'm still a Chrome user because I feel like it's a more polished consumer product, particular in the area of design. Every time I get that F the establishment motivation and open Firefox, I look at the tab structure and the separate url and search bars and close it again. Sad face.
