Last roll of the dice?
It's hard to tell how good, or otherwise, the Priv will be, personally I don't feel the need for a physical keyboard any more for typing but it may well be great for shortcuts. The risk is that, like the Torch 9800 the sliding aspect will result in a failure of the connections between the two parts.
As for the software, until I see what the Android/BB linking is like in the OS I can't say that I would even consider this, and the previously BB-cheering member of my household switched to Android some months ago as the Z10 aged and the associated contract reached upgrade time.
Sorry BB, but I think that the hardware side of the business is probably going to gradually disappear within the next couple of years. And that's a shame...
