Ha ha ha, I think of the Z10 as the opening line of a long seduction that BlackBerry is trying to use to convince loyal customers to stay and to woo competitor's customers into the fold.

It's not all good news for BlackBerry, but given the reported defection rate that the Z10 is producing by pulling in customers from other platforms, their return to profitability last quarter, and the anticipated Q10 coming soon, they seem to be doing okay for now.

To me, the comparative risk of buying a BlackBerry device is that iOS and Android have zero risk of abandonment or of falling off of the leading lap of the smartphone race. That risk would screw up both the resale value and the continued usefulness of the BlackBerry if something bad happens.
