I recently bought a Firefox OS device as my first smartphone and I'm really looking forward to the future of this OS. However, I have been plagued with a number of problems that make really simple tasks incredibly complicated, and I hope you guys are paying attention to bug reports because there are some major issues that have remained unaddressed for an extremely long time.
In any case, an open OS is a necessity and I'm glad that I didn't have to choose between iOS, Android, and WP for my first smartphone. After some major bugs have been addressed, I look forward to being able to buy a high end device on which I can install Firefox OS. I sincerely hope Mozilla continues to give the project a lot of attention and doesn't relegate it to Thunderbird status.
