Oh, you mean phones? And tablets? Touchscreen devices? Who cares!
It's time for Mozilla to focus its mission and scale back its grandiose ambition. We don't need Firefox on phones and tablets--there are already good browsers there. It might be neat, but that's not as important as maintaining the existing browser and developing it further. Desktop/laptop/netbook systems are not going away! I don't need my phone's browser to do everything Firefox can do! (And with Firefox's eternal freezing and stuttering, I don't want it to. How about fixing that before expanding to completely new platforms? What if all the Mozilla devs spent two weeks on that one problem and killed it once and for all?)
Mozilla may end up spreading itself out and doing nothing well--then it will really lose relevance. I'm becoming more interested in other, smaller-scale browsers that are user-focused, without the baggage of the Mozilla project.
Nokia and RIM were in the business of selling devices--Mozilla is not (and should not be!).
IMO, Mozilla's mission should be to make the best desktop/laptop/netbook/systems-with-keyboards-and-mice browser there could possibly be. A secondary mission should be to encourage the open Web--but I'm not convinced that putting Gecko and Firefox on phones and touchscreen tablets is necessary to accomplish that goal. Indeed, if trying to do so hurts Mozilla in the long run, then the open Web will suffer in the long run.
Mozilla needs to set trends, not follow them. It used to do just that, but then Chrome caused a panic, and now Mozilla is pandering.
Get back to your roots, Mozilla! Rise like a Phoenix!
