Eh, it seems a little over-the-top to me. While cool, is it really that practical to have a projector and infrared keyboard in a phone? How useful is the pointing device really going to be, except maybe for when it's in projector mode? If I'm holding the phone, I'd rather use a touchscreen or stylus.
I love Mozilla, but I for one think they got it all wrong. Smartphones are used on the go, on the sofa, maybe in bed, rarely on a desk. Once you're near a desk, you most likely have a computer there. So, I see very little value in the projected keyboard. Moreover, if I were in a position where I actually needed a full keyboard connected to my phone, I think I would really prefer an ordinary docking station with a real keyboard attached. It is just so much more convenient to work with.
Also, I don't care much for the shape of this phone. It may be nice to grip, but seems really bad in the pocket I think.
The video projector is cool for watching movies and stuff though.
