All this kinda reminds me of delays (and delays and delays :-) ) shipping ZX Spectrums and QLs in the early 80s. Sir Clive Quoted a 28 day shipping period, which often got exceeded by months - that was mainly due to a world shortage of RAM chips, and supply being exceeded greatly by the actual Demand.
That was probably the cause of the QL not being that commercially succesful. nice machines though !
