Crosscutter - JQI would not have survived if JQ did not take on the 787's asap. The operating economics of the 330 and the 787 are worlds apart. I suspect JQI is already financially hammered. The 330 would have obliterated it.
'ROIC' is a better measure here.
Dragonman - Product can be replaced. You can make a clapped-out frame look new again with a new interior and fresh coat of paint. Reliability - that may subjective. Well maintained aircraft with the right schedules will be reliable. It is component failure/wear that drives this.
