Geeks, stop trolling.

I think the hardware is a good compromise performance/battery.
The screen is probably the most disappointing aspect, but again it should save on power consumption and everyday user will enjoy the experience of the OS.
1GB RAM is smart also because RAM is a big source of current consumption. It should be enough for a very good Sailfish experience.
Same for the processor, dual-core as a must have today, 1.4GHz for the raw performance.
As for battery, the new iPhone 5S has a 1560mAh one. So 2100mAh is not a bad idea neither.
Bottom line, If they don't mess up with the camera and the device really feels premium, then they will have a hit.

As for the price tag, don't forget that they are small and they need to eat and grow. They probably get a good deal on the phone hardware, so putting a bit of a high price-tag will get hard-core fans (they know about spec, they live with it) and people liking more the design of the phone/OS (they don't give a **** about spec, they enjoy the experience, much like iOS users). Nobody wants the cheap android fanboys to even try Sailfish.

Someone mentioned I2C for the other half communication; where do you get this information ? Is that official ? This is a slow for a communication bus.
